Description

Tests of isospin symmetry in (n,p) and (p,n) reactions at 280 MeV for populating the T=1 isospin triads in A=6 and A=12 nuclei have been performed at TRIUMF. 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 6Li(n,p) and 6Li(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. (Author) (30 refs., 2 tabs., 11 figs.)
