Abstract

The effects of different cluster configurations of 9Be nucleus on the cross-sections of 9Be + 28Si, 9Be + 64Zn, 9Be + 144Sm, 9Be + 186W and 9Be + 208Pb fusion reactions have been explored for the first time using a simple cluster approach. The real potential has been calculated based on the α + α + n, d + 7Li, 3H + 6Li, 3He + 6He and n + 8Be cluster cases of the 9Be nucleus while the imaginary potential is evaluated as Woods-Saxon potential. It has been seen that our results are in agreement with the experimental data. In addition to this, the fusion barrier height (VB) and barrier position (RB) values have been given for each reaction and cluster case.

Highlights

A cluster structure can be evaluated as a structure resulting from the movements of nucleons in a nucleus
The 9Be nucleus can be assumed as α + α + n, d + 7Li, 3H + 6Li, 3He + 6He and n + 8Be cluster structures [2,3,4] the cluster structure of 9Be is not known exactly yet [5]
We examine the effects of different cluster configurations of the 9Be nucleus on the fusion cross-sections (FCSs) of 9Be + 28Si, 9Be + 64Zn, 9Be + 144Sm, 9Be + 186W and 9Be + 208Pb reactions over a simple cluster model. 9Be with low binding energy and cluster structure is an important nucleus in the field of nuclear physics

Summary

Introduction

A cluster structure can be evaluated as a structure resulting from the movements of nucleons in a nucleus. We first obtain the density distributions for α + α + n, d + 7Li, 3H + 6Li, 3He + 6He and n + 8Be cluster cases of the 9Be nucleus. We calculate the real potentials for each fusion reaction using these density distributions within a double folding (DF) model.
