Title: Sub-barrier fusion of {sup 32}S+{sup 48}Ca

Abstract

The fusion excitation function of {sup 32}S+{sup 48}Ca has been measured in a wide energy range, from above the Coulomb barrier down to cross sections in the sub-{mu}b region. The excitation function has a smooth behavior below the barrier with a rather flat slope, and no maximum of astrophysical factor S vs. energy has been observed. However, other interesting features of the dynamics of this system can be noted. In particular, the fusion barrier distribution has an unusual shape with two peaks of similar height, lower and higher than the Akyuez-Winther barrier. Preliminary coupledchannels calculations and a comparison with nearby systems yield information on the possible influence of nucleon transfer channels with positive Q-value.
