Abstract
Angular distributions of differential cross sections and vector and tensor analyzing powers have been measured for transitions in /sup 31/P(d,/sup 3/He)/sup 30/Si and /sup 31/P(d,t)/sup 30/P reactions at E/sub d/approx. =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 (d,/sup 3/He) 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 = l/sub 1/+(1/2 transfers exhibit significantly more pronounced D-state effects than those for j = l/sub 1/-(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 /sup 30/Si and /sup 30/P, and the results have been compared with recent sd--shell-model predictions.
