Abstract

Abstract Polarized deuterons have been used to initiate stripping reactions to determine vector analysing powers for transitions for which the orbital angular momentum l and total angular momentum j of the captured neutron are known. Measurements have been performed at a deuteron energy of about 8 MeV for the target nuclei 9 Be, 12 C, 24 Mg, 40 Ca and 52 Cr. For a given l , there is pronounced difference between the vector analysing powers for j = l+ 1 2 and j = l− 1 2 reactions. The measured vector analysing powers are compared with predictions based on the distorted-wave Born approximation. Effects of variations of optical parameters are discussed. If optical potentials which fit the elastic scattering data are used, the measured vector analysing powers are reproduced for the intermediate-weight nuclei.
