The excitation functions of complete and incomplete fusion reactions of 6Li with Pt nuclei

Abstract

Experimental results from measuring the energy dependences of cross sections of fusion and transfer reactions for 6Li beams and Pt targets are presented. The experiments were performed using the MSP-144 magnetic analyzer; stacks of platinum foils were installed at the focal plane of this analyzer. In the energy range 22.5–42.5 MeV, the energy resolution of the beam hitting the target stack was not worse than 0.25 MeV and that of the transmitted beam was not worse than 0.40 MeV. The yields of products of neutron and deuteron transfer reaction on target nuclei were measured using the γ activity induced in the platinum targets. Thus, excitation functions for transfer reactions were obtained in a wide energy range, including near the Coulomb barrier. It was shown that the basic reaction channel is the deuteron capture from 6Li. In this case, the maximum of the excitation function for 6Li breakup and subsequent deuteron capture lies near the Coulomb barrier of the reaction.
