Abstract
Angular distributions of differential cross sections and vector and tensor analyzing powers have been measured for transitions in (dHeSi and (d,tP reactions at ≊16 Mev. Exact, finite-range distorted-wave Born-approximation analyses have been performed using S- and D-state amplitudes for the three-nucleon systems. Calculations have also been carried out by incorporating realistic three-body wave functions. A j dependence in tensor analyzing powers observed for the first time in (dHe) and (d,t) reactions, can be reproduced in distorted-wave Born approximation calculations only by including a D-state amplitude for three-nucleon systems. We find that the tensor analyzing powers for j=+(1/2 transfers exhibit significantly more pronounced D-state effects than those for j=-(1/2 transfers. The analyzing powers along with the differential cross sections have been used to extract spectroscopic factors for the low-lying levels in and , and the results have been compared with recent sd–shell-model predictions.
