Abstract

Barrier distribution for the ²⁸Si+¹⁵⁴Sm system has been extracted from large angle quasielastic scattering measurement to investigate the role of various channel couplings on fusion dynamics. The coupled channel calculations, including the collective excitation of the target and projectile, are observed to reproduce the experimental BD rather well. It seems that the role of neutron transfer, relative to collective excitation, is in fact weak in the ²⁸Si+¹⁵⁴Sm system even though it has positive Q-value for neutron transfer channels.
