Test Model for Analysis of the Elastic and Inelastic Scattering of 11Li on Proton at 6 to 75MeV=nucleon

Abstract

In the context of the single folding optical model, the elastic scattering of 11Li on proton at the energies 6.0, 62.0, 68.4, and 75.0 MeV=n is analyzed. The real folded potentials of the M3Y and São Paulo interactions have been constructed based on the density distribution of the 11Li halo structure. The densities, Semiphenomenological, COSMA, and Hartree–Fock are used as three forms of the halo 11Li nucleus. The real spin–orbit and imaginary surface potentials are taken in Woods–Saxon form. The recent elastic data at 6.0 MeV=n is well reproduced using the considered potentials. Moreover, these potentials are used to analyze the inelastic scattering data 11Li(p, pA) at 6.0 and 68.4 MeV=n. The obtained results of elastic and inelastic angular distributions are found to be well consistent with the previous studies without normalization factor. The soft dipole resonance is investigated in a 9Li+2n tow-body system of the 11Li nucleus at the energies 6.0 and 68.4 MeV=n. The existence of the low lying structure of the two-body system including the resonance in 1− state of the 11Li nucleus is investigated.
