Title: The {sup 7}Li(d-vector,n{sub 0}){sup 8}Be and {sup 7}Li(d-vector,n{sub 1}){sup 8}Be reactions below 160 keV

Abstract

The polarization observables have been determined for the {sup 7}Li(d-vector,n{sub 0}){sup 8}Be and {sup 7}Li(d-vector ,n{sub 1}){sup 8}Be reactions at beam energies between 80 and 160 keV. A Transition Matrix Element (TME) analysis revealed unique, dominant p-wave solutions for both neutron channels. The polarization observables were compared with distorted wave Born approximation (DWBA) and coupled reaction channels (CRC) calculations. The general features of the data can be reproduced by the CRC calculations when a large target spin-orbit interaction is included. However, serious discrepancies are observed when the TMEs of the theory and experiment are compared.
