Abstract:A microscopic approach is employed to study the optical potential for the 7 Li-nucleus interaction system without any free parameters.It is obtained by folding the microscopic optical potentials of the constituent nucleons of7 Li over their density distributions.We employ an isospin-dependent nucleon microscopic optical potential,which is based on the Skyrne nucleon-nucleon effective interaction and derived using the Green's function method,as the nucleon optical potential.The harmonic oscillator shell model is used to describe the interlal wave function of 7 Li and obtain the nucleon density distribution.The7 Li microscopic optical potential is used to predict the reaction crosssections and elastic scattering angular distributions for the target range from ~(27)Al to ~(208)Pb and energy range below 450 MeV.Generally,the results can reproduce the measured data reasonably well.In addition,the microscopic optical potential is comparable to a global phenomenological optical potential by fitting the presently existing measured data.
Keywords:7Li microscopic optical potential  7Li elastic scattering  folding model
