Theoretical calculation of the p - Li-6 radiative capture reaction

摘要

We present a new calculation of the Li-6(p, gamma)Be-7 radiative capture astrophysical S-factor in a cluster model framework. We consider several intercluster potentials, adjusted to reproduce the Be-7 bound state properties and the p - Li-6 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. (C) 2019 Elsevier B.V. All rights reserved.
