Tensor interaction effects in the 4He(2H, gamma )6Li capture reaction.

Abstract

The spin dependence of the {sup 4}He({sup 2}H,{gamma}){sup 6}Li capture reaction is studied in a deuteron-alpha-particle direct capture model. Nucleon-nucleon tensor interaction effects, manifest through the deuteron and {sup 6}Li internal {ital D} states and through the deuteron-alpha-particle tensor interaction, are included within the {ital d}+{alpha} cluster model. The entrance channel tensor force, calculated from the folding model, is shown to produce relatively minor effects on the calculated reaction tensor analyzing powers compared to those of the {sup 6}Li {ital D} state for center-of-mass energies of proposed experiments ({approx}10 MeV).
