Conclusions and Actions
of the NRDC Meeting in Paris, 27 -30 May 2002
Conclusions
General
1.
The next Technical NRDC Meeting will be held at IAEA Vienna in
late May or early June 2003. The next full meeting will be held in
Brookhaven in spring 2004 (date to be decided).
2.
For new data (1980-1998) the comparison between CINDA and EXFOR
(WP-2002-27) showed that about 75% of all possible EXFOR data are
compiled. This is assumed to be approximately the maximum amount
possible due to the availability of data. As expected the coverage
for pre-1980 data is lower.
General CINDA matters
3.
CINDA coverage was reviewed and it was felt that all major
journals are adequately covered. Future coverage of progress
reports may not necessarily be important nor need be continued.
4.
The future NRDC cooperation on CINDA was adopted as proposed in WP
2002-28. All centers, except ATOMKI, volunteered to contribute
CINDA input to the new system (neutron and/or charged particle
data).
5.
CINDA 2002 will be published as Supplement. At the same time the
CD will be produced again by NEA-DB. NDS will consider publishing
a final CINDA archival book, spread over 2 years in 2004/5, based
on the new CINDA2001, i.e. including also CPND and photonuclear
data.
Dictionaries
6.
The proposal of Memo CP-C/287 (WP 2002-2, p.1) is accepted, i.e.
there will be only one particle dictionary.
7.
Dictionaries must still be transmitted in the TRANS format.
8.
A new Nuclides dictionary (as a replacement to dictionary 27) will
be produced, which will be extracted from the Nuclear Data Wallet
cards database. (See also Action A11).
General EXFOR matters
9.
The proposed security measures as outlined in WP-2002-19 regarding
the NDS Open area were agreed. Hence a username NDSX4 must be
entered (no password is required as yet) and this user can only
put and get files. This user, along with all others, cannot
modify, delete or overwrite existing files. File management will
be carried out by the holder of the XMAN token, currently
allocated to user SCHWERER.
EXFOR dictionary codes and coding rules
10.
Following from WP-2002-3 (Units for particle and product yields,
Dict.25) it was agreed that:
PRT be used for the outgoing particle, i.e. SF3, or SF7
PRD be used for reaction product, i.e. SF4
INC used for incident projectile, i.e. SF2
REAC used for reaction (with FIS used for fission), in general SF2-3
PC for percent or per 100 incident particles
Consequently, the unit PRD/FIS should be allowed.
11.
Page number format as presented in WP-2002-4 has been adopted,
i.e. to allow alphanumeric characters in the page number field in
REFERENCE.
12.
The proposed new heading EN-CM-TOT is NOT needed, but the
definition of EN-CM needs to be clarified (WP-2002-8). (See also
Action A34).
13.
The units MUB/SRGEVC and the new particle code AP (anti-proton)
are adopted (WP-2002-10)
14.
The proposed code NSF is not needed nor the other new quantities
of CP-E/004 (WP-2002-10).
15.
(WP-2002-12) Agreed that UND and DEF (in REACTION SF5) should not
be used, but that (DEF) can be used if the compiler is uncertain.
16.
A working group will be formed in order to investigate the way in
which high energy physics data can be coded in EXFOR, including
the coding of fundamental particles. The following participants
agreed to sit on the committee: Chukreev, McLane, Kato, Otuka,
Tarkanyi. See also Action A36.
17.
The proposed code 2XL as a modifier (REACTION SF8) as proposed in
CP-C/305 (WP-2002-15) is not necessary and therefore has been
rejected.
18.
The use of a zero value in the DATA-ERR field is allowed (CP-C/306
= WP-2002-16) except when the data are digitized. Required for
large datasets sent by the author when the accuracy representation
of the field is not sufficient to have a finite value. The
DATA-ERR column cannot contain only zeros, in this case the column
should not be included at all and a comment included under
ERR-ANALYS.
19.
The proposed use of 4-momentum transfer and momentum distribution
data is agreed as in CP-C/295 = WP-2002-6
20.
(WP 2002-11) Nuclide codes are from now on allowed in REACTION SF7
(Particle considered). If the resulting REACTION string can no
longer fit in cols. 12-66, continuation onto the next record will
follow the same rules as for DECAY-DATA (i.e., line breaks are
allowed only after one of the commas which separate subfields)
21.
(WP 2002-12) The new headings PART-OUT and ELEM-MAX will be
introduced in dictionary 24.
Actions
General
1.
All (Continuing) Support the joint project of Russia, Ukraine
(UkrNDC) and Belarus (Minsk-Sosny) on development of Internet site
structure and web pages for nuclear databases and related
software. This support will include establishment of contacts of
project initiators with European, US and other centers and
organisations interested in collaboration, cooperation or
partnership.
2.
Dunaeva (Continuing) Keep other centers informed on the status of
the proposed project.
3.
All All recognized policy papers for consideration by the NRDC
members need to be prepared and distributed four weeks before the
Annual NRDC meeting. This will ensure adequate thought and
discussion prior to the meeting.
4.
NDS Assist the Slavutych Laboratory, Ukraine, in upgrading their
NDIS (Telnet-based nuclear data system), which has not been
upgraded since 1999.
5.
NDS Consider organizing an EXFOR compilers' workshop, either
separately or adjacent to next years' Technical NRDC Meeting.
6.
All Check the "Citation Guidelines" document (available from NNDC
and NDS websites) and send updates to NDS who will be responsible
for maintenance from now on.
CINDA
7.
NEA-DB Submit the area 2 CINDA neutron master file in the new
format to NDS and NNDC.
8.
NEA-DB Send to NNDC the area 2 CINDA master file in exchange
format for conversion to the new format.
9.
NNDC Compare the two versions of area 2 master file as outlined
above.
10.
CNDC (Continuing) Compile all Chinese experimental works (journals
and conference proceedings) for CINDA and send to NDS in Reader
format. Consider the possibility of including in the
"Communication of Nuclear Data Progress" journal abstracts/brief
publications of all nuclear data works undertaken in China.
Dictionary system
11.
McLane: To produce a format for the new Nuclides dictionary (see
Conclusion C8) and provide a program for the production and
updating of this dictionary from the Nuclear Data Wallet cards
database.
12.
All (Continuing) To ensure that the "wild cards" can be used for
REACTION SF7 (Particle considered) in Dictionary 36 .
13.
NDS (Continuing) To remove the restrictions “for photonuclear data
(only)” from all dictionaries at their earliest convenience.
General EXFOR matters
14.
All Test V. Zerkin's experimental new "EXFOR relational" web
interface http://zlinux.iaea.or.at/~zerkin/x4s/indx.htm and send
feedback to NDS
15.
NDS Distribute new copies of the "Relational EXFOR" CD-ROM to the
participants of this meeting.
16.
All (Continuing) To check/retransmit all entries included in the
list of pending retransmissions by McLane distributed at the 2001
NRDC meeting.
17.
Dunaeva (Continuing) To make a benchmark test of Chukreev's code
TEST-EXF vs. CHEX
18.
CPND centers (Continuing) To check the list of references
identified as missing in EXFOR during the CRP on Medical
Radioisotope Production, and distributed by Tarkanyi; communicate
with Tarkanyi and NDS concerning which items they will compile
from their area of responsibility. References not covered in this
way will then be available for compilation by others.
19.
NEA-DB,NDS (Continuing) To convert remaining 60000 and 70000
series entries to proper EXFOR entries of area 2 and 3.
20.
All (Continuing) In view of the poor statistics for EXFOR
compilations of recent works, all centers should give higher
priority to new works.
21.
McLane (Continuing) Send to all participating centers a memorandum
of understanding that defines compilation responsibilities
resulting from the agreement with Phys.Rev.C (on EXFOR archiving
of experimental data published in Phys.Rev.C).
22.
Dunaeva, Chukreev (Continuing) Once the agreement between NNDC and
the publishers of Phys.Rev.C has been put into operation, try to
establish a similar agreement with the publisher of Yadernaya
Fizika.
23.
NEA To transmit the corrected EXFOR entries containing correlation
data sent earlier by McLane.
24.
All: Send their area’s EXFOR master file to NDS for comparison.
25.
All: Send list of known errors in other centers’ entries to NDS.
26.
NDS: Compare all master files received with the NDS file, and as
far as possible correct them (with help of other centers).
27.
NDS Make available to all centers the “final” EXFOR master file,
together with a matching set of dictionaries.
28.
All concerned Transmit with highest priority all preliminary EXFOR
TRANS files which have been held back because of pending
corrections. Problematic entries should be excluded temporarily
from transmission (until agreement on the correction is reached)
to speed up the procedure.
29.
JCPRG After upgrading, send HENDEL (Web-based EXFOR editor) to the
other centres for testing and comments.
EXFOR dictionary codes and coding rules
30.
All (Continuing) To consider and propose methods for coding
fundamental particles in SF4, in particular those negatively
charged (e.g. negative pions).
31.
Tarkanyi: To produce a list of quantities related to Product
Yields and Thick Target Yields with a detailed explanation and
including reference to an appropriate paper as an example.
32.
McLane/Schwerer: To improve the LEXFOR entry on 'Correlations'
with respect to the clarifications requested in WP-2002-5.
33.
McLane/Schwerer: To produce new LEXFOR entries relating to the
various quantities discussed in WP-2002-13.
34.
Schwerer: Modify the definition of EN-CM in dictionary 24 to be
energy of the projectile relative to the target.
35.
Chukreev The REAC in WP-2002-12 (Memo CP/A-122) should be recoded
from
79-AU-197(AP,ABS),,SIG/DN,,,EXP as
79-AU-197(AP,X)ELEM/MASS,,SIG/DN,,,EXP
The range of ELEM and MASS will be defined in the COMMON section by
ELEM-MIN, MASS-MIN, ELEM-MAX and MASS-MAX. These codes will need to be
added to the dictionary.
Thus the data under the heading PART-OUT can remain the same as
entered previously.
36.
Working Group (On coding of high energy data in EXFOR, see
Conclusion C17) To investigate the coding of high energy physics
data and fundamental particles, and produce a report for
discussion at the next meeting.
37.
McLane To correct the LEXFOR entry for the proposed coding of
4-momentum transfer (WP-2002-6).
38.
McLane To check whether there is a LEXFOR entry on the new process
code FUS (total fusion, Dictionary 30); if not, provide such an
entry.
39.
Schwerer (WP 2002-14) Check whether the quantities
LS/SEQ,POL/DA,,D
PAR,POL/DA,,TAP
SL/SEQ,POL/DA,,D
exist in the file, and delete them in Dictionary 36 if this is not the
case.
40.
Schwerer (WP 2002-14) For the codes 20/PAR,POL/DA,,TAP and
PAR/20,POL/DA,,TAP: pick one of these options, maintaining
consistency with other similar quantity codes, and update
dictionary 36 (and any affected entries) accordingly.
41.
Schwerer (WP 2002-14) Correct the expansion of NN,POL/DA,,ANA to
"Spin correlation parameter".
42.
McLane Try to resolve the problems in order to define the various
polarization quantities for LEXFOR and dictionary 36 consistently.
43.
Schwerer Delete RCL from dictionary 33.
Miscellaneous
44.
