Fusion barrier distribution derived from quasielastic excitation functions in 11 B, 13 C, 13 C+ 209 Bi reactions

Abstract

The representations of fusion barrier distribution were derived from the quasielastic excitation function measured at the backward angle in B11, C12, C13+Bi209 reactions at energies around the Coulomb barrier. The experimental fusion barrier distributions were compared with the predictions of simplified coupled-channels fusion (CCDEF) calculations with inclusion of various channels coupling because of low-lying inelastic states of target and one and few nucleon transfers. The influence of neutron transfer coupling on fusion barrier distribution has been discussed. Show more
