A0348 4 6 CORRECTION /By authors/ The total cross section have been A0348 4 7 expressed as sigma(p,2n)=sigma-84+ delta-sigma'+ A0348 4 8 +delta-sigma'', where delta-sigma' and delta-sigma'' A0348 4 9 are correction terms. The correction delta-sigma' is A0348 4 10 obtained from the intensity of the 68.5 keV A0348 4 11 transition and from the intensity difference of the A0348 4 12 58.6 and 25.6 keV transitions. Delta-sigma'' should A0348 4 13 account for the feeding of the ground-and the 9.2 keV A0348 4 14 states by transitions from levels higher than 84.2 keV.A0348 4 15 HISTORY (20120120A) NDS(VZ): REL-REF: ND/B->NDS A0348 4 16 ENDBIB 14 0 A0348 4 17 NOCOMMON 0 0 A0348 4 18 DATA 5 15 A0348 4 19 EN MISC MONIT DATA DATA-ERR A0348 4 20 MEV MEV MB MB MB A0348 4 21 7.23 7.17 75. 0.8 0.3 A0348 4 22 8.85 8.79 120. 12.3 1.3 A0348 4 23 10.10 10.05 170. 50. 3.
