Abstract

Tests of isospin symmetry in (n,p), (p,p’), and (p,n) reactions at 280 MeV populating the T=1 isospin triads in A=6 and A=12 nuclei have been performed. Distorted-wave impulse approximation (DWIA) calculations for the A=12 triad where the known ft asymmetry is included in the analysis show good agreement with experimental (n,p) and (p,p’) data. Angular distributions for ${}^{6}{Li}$ (n,p) and ${}^{6}{Li}$ (p,p’) cross sections differ significantly at finite values of momentum transfer (q) and do not agree with DWIA calculations. However, this discrepancy may become negligible upon extrapolation to q=0.
