Abstract

The cross sections are calculated for the both elastic and inelastic scattering of 6He from 12C and 4He. A phenomenological optical potential is used to describe the elastic scattering. 4He is taken as spherical and inelastic couplings to the first excited states of 6He and 12C are described with collective rotational model and coupled-channels method. Deformation lengths for 6He and 12C are determined from semi-classical nuclear level density model by using Laplace-like formula for the nuclear level density parameter. The comparison of the predicted and the measured cross sections are presented to test the applicability of nuclear level density model to the light exotic nuclei reactions. Good agreement is achieved between the predicted and measured cross sections.

Highlights

After the use of radioactive ion beams (RIBs) in the mid-1980s [1], heavy-ion induced reactions, which involve light exotic nuclei, have become a subject of great interest for both theoretical and experimental studies
We have proposed a Laplace-like formula for the energy dependence of the nuclear level density parameter, which is the main parameter of Nuclear level density (NLD), including collective effects [6]
With this procedure we were able to obtain the energy of the first excited state as a function of deformation parameter

Summary

Introduction

After the use of radioactive ion beams (RIBs) in the mid-1980s [1], heavy-ion induced reactions, which involve light exotic nuclei, have become a subject of great interest for both theoretical and experimental studies. Nuclear level density (NLD) could have been one of the candidates but it always has been a problem to describe the low-lying collective states for NLD models [4, 5]. We have proposed a Laplace-like formula for the energy dependence of the nuclear level density parameter, which is the main parameter of NLD, including collective effects [6].
