A034800100022 COMMENT /By authors/ Two methods were used in the cross A034800100023 section determinations- a standard activation method A034800100024 for the (p,n),(p,3n),(p,p+n)+(p+d) reaction and A034800100025 in-beam gamma-ray method in case of the (p,2n) A034800100026 reaction.

The correction delta-sigma' is A034800400010 obtained from the intensity of the 68.5 keV A034800400011 transition and from the intensity difference of the A034800400012 58.6 and 25.6 keV transitions. Delta-sigma'' should A034800400013 account for the feeding of the ground-and the 9.2 keV A034800400014 states by transitions from levels higher than 84.2 keV.A034800400015 HISTORY (20120120A) NDS(VZ): REL-REF: ND/B->NDS A034800400016 ENDBIB 14 0 A034800400017 NOCOMMON 0 0 A034800400018 DATA 5 15 A034800400019 EN MISC MONIT DATA DATA-ERR A034800400020 MEV MEV MB MB MB A034800400021 7.23 7.17 75. 0.8 0.3 A034800400022 8.85 8.79 120. 12.3 1.3 A034800400023 10.10 10.05 170. 50. 3.
