Cross sections from 0° to 10° (lab) have been measured for ground-state Gamow-Teller transitions for the reactions ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$(n,p${)}^6$He, ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$(n,p${)}^{12}$B and ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$(n,p${)}^{13}$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 (σ) have been obtained and are compared with existing (n,p) and (p,n) data. The volume integrals (${\mathit{J}}_{\mathrm{\sigma }\mathrm{\tau }}$) for the spin-flip isospin-flip part of the effective nucleon-nucleon interaction have also been obtained and are compared with theoretical predictions.
