Abstract

Study of fission reactions induced by 4,6 He and 7 Li beams on 209 Bi and 208 Pb targets, leading to the production of 210,212 A compound nuclei, was performed. It was shown that the fission excitation functions for the three reactions 4,6 He + 209 Bi and 7 Li + 208 Pb had similar behavior within the experimental error for a broad range of energy. More likely, halo structure of 6 He is not reflected on the fission reaction mechanism. Otherwise, a large value of the fusion cross section was observed so far, as it could be expected in the case of weakly bound character of 6 He projectile.

Highlights

In the past few years, in different scientific centers, intensive experimental studies have been performed using secondary beams formed from the radioactive products of nuclear reactions [1, 2]

Summary

Introduction

In the past few years, in different scientific centers, intensive experimental studies have been performed using secondary beams formed from the radioactive products of nuclear reactions [1, 2]. There has been a growing trend to use secondary beams as a means of investigating the interaction cross sections of these exotic nuclei with the target nuclei. These data help getting information on the structure of nuclei far from the line of stability, on the distribution of nuclear matter and on charge radii. The line represents the theoretical calculations using PACE-4 code
