The Excitation Functions of Complete and Incomplete Fusion Reactions of ~6Li with Pt Nuclei

摘要

Experimental results from measuring the energy dependences of cross sections of fusion and trans-fer reactions for ~6Li beams and Pt targets are presented. The experiments were performed using the MSP-144magnetic analyzer; stacks of platinum foils were installed at the focal plane of this analyzer. In the energy range22.5-42.5 MeV, the energy resolution of the beam hitting the target stack was not worse than 0.25 MeV and thatof the transmitted beam was not worse than 0.40 MeV. The yields of products of neutron and deuteron transferreaction on target nuclei were measured using the y activity induced in the platinum targets. Thus, excitation func-tions for transfer reactions were obtained in a wide energy range, including near the Coulomb barrier. It was shownthat the basic reaction channel is the deuteron capture from 6Li. In this case, the maximum of the excitation func-tion for ~6Li breakup and subsequent deuteron capturelies near the Coulomb barrier of reaction.
