Measurement of Quasi-elastic Scattering: to Probe $^{28}$Si+$^{154}$Sm Reaction

Abstract : We discuss the role of channel coupling of 28Si on fusion mechanism with permanently deformed target 154Sm. To this end, we analyze the experimental quasi-elastic cross sections at a large backward angle and quasi-elastic barrier distribution for 28Si+154Sm system using the coupled-channels approach. While earlier studies have reported the rotational excitation of 28Si playing role on fusion with spherical and near spherical target nuclei, we find its vibrational excitation as origin of observed barrier distribution for 28Si+154Sm system. Our study also reveals significant influence of channel couplings on the surface diffuseness parameter of an inter-nuclear potential supporting the earlier observations.
