Subject: Comments on TRANS A031

Please find below our comments on TRANS A031. Entries for which we consider correction andretransmission by CAJaD very important are labelled with *). Several corrections were done by
NDS before transmitting this TRANS to the other centres; these are mentioned here for
information to CAJaD and are marked in the list below with "CORR.NDS". CAJaD is asked tocheck the remaining errors for necessary correction and potential retransmission.

Comments on TRANS A031

General comments:
Alter flags in col.80:---------------------On this TRANS only used in ENTRY and SUBENT records. It would be helpful to the receiving
centers if alter flags C, I, D, R would be used in col.80 of individual lines as described on page 2.5of the Exfor Manual.
Codes IND and UND in REACTION SF5:---------------------------------There have been discussions about the correct use of these codes for years and I am aware thatexisting CPND entries, particularly from the B area, are not completely consistent with each other.
Therefore I will not comment on al "doubtful" usages, in particular since these codes are normallynot used as essential retrieval criteria (with some exceptions). However, to keep inconsistencies toa minimum, I want to restate the following:- IND should be used only if the same reaction (SF1 to SF4) exists also in CUMulative form,
giving a different value (at least in principle). It makes only sense if the reaction channel is not
specifically defined (i.e.SF3 = X or = F). If a certain channel, e.g. (P,2N+2P), is given, production
by beta decay is excluded (because in this case SF3 is different) and therefore IND and CUM are
not applicable. (CUM also includes internal transition; however, if only internal transition but nobeta decay is included, the correct code is M+ for partial contribution, and no code is needed for
total sum of isomers.)
If e.g. SF4 = Be-7 or Be-10 (entries A0529, A0530), production by beta decay is not possible andtherefore IND should not be used (because the REACTION code without IND means exactly thesame).
- UND means that the sum of particles in SF3 is not meant as individual particles but as sum ofemitted nucleons, e.g. 3 neutrons and 3 protons. Therefore UND is redundant, and should not beused, if SF3 = X (e.g. several subentries of A0536).

DECAY-DATA:----------An entry under DECAY-DATA giving only the nuclide but no other information is not meaningful
although it is not illegal (entries A0535, A0536). At least the half-life should be coded (if thevalues used by authors are known); or give only free text "no information given by authors"
without nuclide code.

Line 30: -G missing

Why is UND missing in SF5 ? Not consistent with other subents.

A0530

Lines 27,28 identical

A0531

2REACTION....43-TC-96,IND/M+,SIG should beeither....43-TC-96-G,M+,SIG(g.s. with partial m.s.contribution)or....43-TC-96,,SIG(if measured quantity (almost) equal total c.s.)(CORR.NDS)

A0532*) 2-4

Isomeric cross section ratios must be coded as IMPLICIT
ratios, e.g. (subentry 2):(78-PT-198(D,2N)79-AU-198-M/G,,SIG/RAT,,,EXP)
Also the REL modifier in SF8 should be unnecessary since it isa ratio anyway.

A0535

RAD-DET: 9-F-19 should be 9-F-18

2(CORR.NDS)

A0536*) 5,20,21 Metastable state given as -M in REACTION SF4 should not be
defined by heading LVL-NUMB but by it's half-life (underDECAY-DATA).
6
REACTION SF4 has -G but DATA section and LEVEL-PROP give
LVL-NUMB = 2: this is a contradiction. Anyway LVL-NUMB should
be used with PAR in SF5 but not for -G and -M states.
Units PER-CENT illegal for LVL-NUMBER, use NO-DIM. (CORR.NDS)

Check whether REACTION SF4 should contain -G or -M extension(metastable states exist which partly decay by beta decay,
partly by isomeric transition, therefore it is unlikely thatthe total cs - which is coded without -G or -M - was measured).

A0538

4IND/M+ in SF5 should be deleted - probably total cs measured(-M has 100% isomeric transition, and no cumul.productionby beta decay possible)

A0540

2The angles explained in lines 5-8 should be given in COMMON
section too, using headings ANG1, ANG2 etc.
