Nuclear level density as a tool for probing the inelastic scattering of ⁶He

Abstract

The cross sections are calculated for the both elastic and inelastic scattering of 6 He from 12 C and 4 He. A phenomenological optical potential is used to describe the elastic scattering. 4 He is taken as spherical and inelastic couplings to the first excited states of 6 He and 12 C are described with collective rotational model and coupled-channels method. Deformation lengths for 6 He and 12 C 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.
