Comments on TRANS 2140
21307*) All subentries: There is a confusion about the type of average crosssections given. SF8 says 'SPA' (spectrum average) with an entry under
INC-SPECT defining a very broad incident neutron spectrum. If SPA isused, then the data are understood to be averaged over the broad
spectrum as defined under INC-SPECT, and a mean EN value must be given
under the heading EN-MEAN, EN-DUMMY or equivalent. This is however notthe case; instead, narrow energy intervals are given in the DATA
sections using EN-MIN and EN-MAX. For this type of data, SF8 should be=AV (averaged) instead of SPA, and the broad spectrum as explained
under INC-SPECT should not be important since the cross sections aregiven for rather narrow EN intervals. Spectrum averaged data arenormally given for only one (mean) energy value, not for a table ofvalues.
Please clarify whether these data are 'AVeraged' or 'SPectrum Averaged'and retransmit.
21308*) Subent 2: Secondary energy (E-EXC) only legal for partial quantity.
In this case, heading MISC should be used instead.
Subent 3: 1) REACTION code TER/BIN,FY not in dictionary. Is this a newquantity? Note that TER/BIN so far is used for ratios only
(TER/BIN,SIG/RAT) so that the denominator of the ratio given here would
be a ratio in itself. (?)2) Dimension: since a ratio of 2 fission yields is given, should thedimension not be NO-DIM?
3) The definition of the "complete" quantity, given by this reaction
ratio, is not clear, need either new proposal for dict.36 (item 1above) with explanation and/or explanation in free text of thissubentry and/or correction of units. Since a ratio is given, perhaps
SIG could be used instead of FY? Please retransmit.

1) Delete PAR from REACTION SF52) DECAY-DATA missing

22329 and 22330, subent 1, MONITOR: SF 4 missing
22329 Subents 2,3: SF4 in REACTION missing
22331003: Change units of DATA (STF) to NO-DIM22334*)

1) EN missing2) Subentries 2-37: ratio of 2 reactions with same dimension must
always be given in units NO-DIM (not PER-CENT).

Comments on TRANS 410541244.002*) KT (incident particle spectrum temperature) must have units MeV or
equivalent, not DEG-K.
41248*) and 41249*) Since REACTION SF8=SPA, EN must be replaced by EN-MEAN or
EN-DUMMY (or KT), and more information under INC-SPECT should be given.

Comments on TRANS 410641201*)

I don't understand the difference between subentries 2-4 on one handand 8-10 on the other. PAR in SF5 in subentries 2-4 should be deleted(the quantity PAR,DE is obsolete), and judging from the references(the 94GATLINBURG paper and the English abstract of the YK artice) it
seems to be the same quantity. Subent 8 says "correlated to subentry 2"(and the same for subents 9/3 and 10/4) but it is not explained how they
are correlated. Could it be that subentries 8-10 etc. SUPERSEDE
subentries 2-4? Please check and retransmit (explain correlations
between subentries and/or correct reactions and/or delete any supersededsubentries)
