Energy dependence of the Gamow-Teller strength in p-shell nuclei observed in the (n,p) reaction.

Cross sections from 0{degree} to 10{degree} (lab) have been measured for ground-state Gamow-Teller transitions for the reactions {sup 6}Li({ital n},{ital p}){sup 6}He, {sup 12}C({ital n},{ital p}){sup 12}B and {sup 13}C({ital n},{ital p}){sup 13}B from 60 to 260 MeV. The 90-m station at the Weapons Neutron Research facility at Los Alamos National Laboratory was used to obtain these data. Unit cross sections ({sigma}) have been obtained and are compared with existing ({ital n},{ital p}) and ({ital p},{ital n}) data. The volume integrals ({ital J}{sub {sigma}{tau}}) for the spin-flip isospin-flip part of the effective nucleon-nucleon interaction have also been obtained and are compared with theoretical predictions.
