The scattering cross sections for6,7Li +nreactions

Abstract

We investigate the continuum-discretized coupled-channel analysis to the integrated elastic and inelastic scattering cross sections for 6,7 Li + n reactions. We used the Jeukenne- Lejeune-Mahaux effective nucleon-nucleon interaction and optical model potential at incident neutron energies below and above 10 MeV, respectively. The calculated elastic and inelastic scattering cross sections with observed incident energies are almost in good agreement with experimental and evaluated data. cross sections for 6,7 Li at incident neutron energies below 10 MeV by using optical model potential (OMP) (7,8) and above 10 MeV by using JLM. We adjust the normalization constants for the OMP, because the agreement of the calculated cross sections with the data in very low incident energies of the neutron is insufficient without any adjustments. The energy dependent normalization constants, real part λv and imaginary part λw, of the OMP and JLM are determined explicitly from the integrated elastic cross section data, respectively. Comparing the results of calculations with experimental data, we discuss that the present CDCC calculations, which reproduce the experimental data observed in incident energies higher than 10 MeV with the single folding potential of the JLM and in lower energies with introducing the normalization factors for the cluster folding potential of the OMP.
