Abstract

We present a new calculation of the $^{6} Li (p, I^^{3})^{7} Be$ radiative capture astrophysical $S$ -factor in a cluster model framework. We consider several intercluster potentials, adjusted to reproduce the $^{7} Be$ bound state properties and the $p -^{6} Li$ elastic scattering phase shifts. Using these potentials, we calculate the astrophysical $S$ -factor, obtaining a good agreement with available data, and the photon angular distribution. Finally, we discuss the consequences of a hypothetical resonance-like structure on the $S$ -factor.
