Title: Measurements of evaporation residue cross sections for the fusion reactions {sup 86}Kr+{sup 134}Ba and {sup 86}Kr+{sup 138}Ba

Abstract

We measured evaporation residue (ER) cross sections of the fusion reactions {sup 86}Kr+{sup 134,138}Ba to investigate the effect of the shell structure of the interacting nuclei on the fusion process. The measured ER cross sections for the reaction {sup 86}Kr+{sup 138}Ba have a sizable component, 37 nb, at the excitation energy (E{sub ex}) of 12.1 MeV. However, there is no evaporation residue for the reaction {sup 86}Kr+{sup 134}Ba below the energy E{sub ex}=24.7 MeV. This result suggests that the neutron shell closure (N=82) of {sup 138}Ba plays a crucial role in the formation of the compound nucleus.
