Reply to CP-C/313, 314, 315 and
NNDC’s comments on PRELIM.E021, CP-E/013, 016
thank you very much for Vicki’s carefully checking and giving useful comments and suggestions
to help our compilations of PRELIM.E021. The following is reply for them:Date:

From:
Subject:

1. Longitudinal momentum LP (CP-C/313)
We are satisfied with Vicki’s proposals CP-C/313 1)-3).
2. Elementary particle production cross sections (PRELIM.E021.E1706, E1711, CP-C/314)
The preliminary E021 includes elementary particle production cross sections for anti-proton (inE1706) and positive kaon (in E1717). CP-C/314 proposes the following compilation for them:
REACTION
REACTION(6-C-0(D,X)1-AP-1,,DA/DP)(6-C-0(KN,X)0-KP-0,,DA/DP)

E170600600003
E171700200003

The expression for anti-proton looks good, while we prefer to use 1-KP-0, where we suggest
Z would be the absolute value of electric charge. We also propose that A denotes absolute valueof baryon number (this with the example of CP-C/314). We hope to have more discussion for K+.
We withdraw E1717 from final TRANS.E021 and wait a conclusion of High Energy WorkingGroup).
3. Angular range codes: ANG1-MIN, ANG1-MAX... (PRELIM.E021.E1711, CP-E/013)
Vicki proposed to treat these angular ranges as additional information on 16 December. In thepresent paper (W.Q.Shen et al., Phys.Rev.C56(1997)1996, compiled as E1711 inPRELIM.E021),
1) Two polar angular ranges for two protons, 10 deg<θ<160 deg, would rise from the limitationof measurement technique, which cannot cover most forward and backward direction;2) The authors would not expect that this theta range affects current experimental azimuthal
angular correlations.
So we conclude that these polar angular ranges can be treated as additional information. We
also withdraw CP-E/013 which proposed new codes ANG1-MIN, ANG1-MAX, ANG2-MIN
and ANG2-MAX.

4. Beam from projectile fragment separator: PRJFS (PRELIM.E021.E1721, CP-E/016)
In CP-E/016, we proposed new codes PRJFS (Secondary beam from projectile fragmentseparator) which is used in E1721 of PRELIM.E021. Vicki’s counterproposal is PRJFS2. The
last 2 probably expresses “secondary”. It seems to be good. But now the length of code inDict.18 (Facility) is limited to be less than 5. So now I propose to use PRJFS again if there isno other proposal.
5. Reaction field particle considered (PRELIM.E021.E1748)
We support Vicki’s proposal for the expression of correlated particles in SF7. The following is acoding example for PRELIM.E021.E1748.020 using the proposal:(DA/DA/DE,A/T/A-T or DA/DA/DE,T/A/T-A ?)SUBENT
