Subject: Comments on TRANS O006 - O008

Please find below our comments on these TRANS files. Errors corrected by NDS are flaggedwith [NDS], entries where retransmission is requested with *). Versions containing thecorrections by NDS are available from the NDS open area.

TRANS O006
General remarks:1)Nuclide codes under RAD-DET and DECAY-DATA should have an isomer code (usually-G or -M) if the nuclide has an isomer registered in dictionary 27. (If there is no isomer, -G
must not be used.)
2)REL-REF: References by the same group as given under REFERENCE, describing aspects
relevant to the present work (e.g. experimental details) must be given under REFERENCE
rather than REL-REF. REL-REF is meant for works by othor authors (e.g. in case of criticism,comparing results etc.)(O0276, O0277)

O0320.064 Lines 3-5: one pair of parentheses missing: ( () = (()+()) )[NDS]

O0321.002-016*): Inconsistency between REACTION DA/DA/DE and independent
variables given. DA/DA/DE requires 2 angles and 1 secondary energybut here 2 secondary energies but no angle are given. Since thedata are labelled relative with ARB-UNITS, the dimension of theunits does not help to clarify the correct coding. Please either
add the needed variables (also constant angles given in COMMON
section would be possible) or correct REACTION appropriately.
Since 2 secondary energies are given, possible solutions would beDA/DE/DE (which still requires one angle) or just DE/DE (whichwould have to be added to dict.36). In those subentries with morethan one type of outgoing particle, i.e. the subentries with(P,N+P), in addition appropriate codes in REACTION SF7 are needed
to define the particles to which the given angles and/or secondary
energies belong, e.g. DA/DE/DE,N/N/P (see dictionary 36).
O0323.043*)

Units MU-B/SR inconsistent with REACTION code SIG. Probably units
should be MU-B, but this should be checked by originating compiler
and be retransmitted.

O0323.046-049*): ANGle given which is inconsistent with SF6 = SIG. If this isordinary integral cross section (which does not depend on angle),
ANG in COMMON section should be removed. If this is the differential
cross section at the angle given, multiplied by 4PI (therefore
having units MB or equivalent), change REACTION to ,DA,,4PI.

O0334.002,005,006,008,009,011-014: Isomeric fission cross section ratio: since
this is numerically
identical to a fission yield ratio, we propose to change SIG to FY
here. This is also the quantity mentioned in the TITLE and the way
these data are usually called and retrieved. [NDS]
O0334.004: This REACTION combination, consisting of 6 individual reactions,must be rewritten to be better retrievable and better readable tothe user, even if these 6 reactions were measured individually.
1) Isomeric sums corresponding to the total reaction must bewritten as simple reaction without any isomer extension, e.g.
the sum(92-U-0(P,F)49-IN-117-M,IND,SIG)+(92-U-0(P,F)49-IN-117-G,IND,SIG)
is not legal and must be replaced by the simple reaction(92-U-0(P,F)49-IN-117,IND,SIG).
2) CD-117(CUM)+IN-117(IND) = IN-117(CUM)
3) Although numerically there is no difference between fission
cross section ratios and fission yield ratios, it is recommended
to code such data as fission yield ratios because this is the way
users will most likely try to retrieve them.
Therefore, the REACTION for this subentry should be simply:((92-U-0(P,F)49-IN-117,IND,FY)/(92-U-0(P,F)49-IN-117,CUM,FY))
How this was determined (measuring some or all of the 6 individualcomponents originally coded) could be explained in free text.
[NDS], retransmission with new free text recommended
O0334.007,010: see comment on subentry 4 above (same case with different
fissioning nuclides)
O0336*) and O0337*), all subentries: TITLE says "fission" but all data arecoded as (P,X).
Unless there is a reason for this, we propose to change thereactions to (P,F). For the ratios, you might consider to change
the coding to FY/RAT (see comment on entry O0334).

O0365.003, line 8: delete illegal col.80 [NDS]
O0365.003-019*): SIG and units MB incompatible with independent variable ANGle.
Should SF6 be = DA and units be = MB/SR ?
O0374.002-005*): REACTION code KE,FF,REL,EXP not compatible with DATA section.
KE,FF is defined as energy of fission fragments (units MEV for DATA).
But here the energy of the fission fragments is the independent
variable instead of the data measured. Propose to discuss at theforthcoming NRDC meeting how such data should be compiled.
O0374.006-009*): (P,F)MASS,,SIG,REL (with ARB-UNITS): it seems that this
could be coded as (relative) mass (chain) yields rather than crosssections.

O0375.006-009*): Probably codes for SF7 should be added to define the kind ofangular correlation, e.g. COR,FF/FF (see dictionary 36)
O0379.002,003: REACTION SF5: replace IND by PAR [NDS]

O0383.002-004*): REACTION(P,F)MASS,,PY,,,EXP not correct. For fission
product yields SF6 must be = FY. Correct code is probably
CHN,FY (total chain yield) or perhaps PRE,FY or SEC,FY(primary or secondary fission-fragment yield). See LEXFOR under"Fission Yields".
O0383.008-012*):TRANS
