Optical model analysis of p+6He scattering over a wide range of energy

Abstract

Optical model analysis of proton elastic scattering from 6 He has been carried out for eight sets of elastic scattering data at energies of 24.5, 25.0, 36.2, 38.3, 40.9, 41.6, 71.0 and 82.3 MeV/nucleon, respectively. The vector analyzing power and differential cross section for the elastic scattering of 6 He nucleus from polarized protons at 71 MeV have been analyzed in the framework of the optical model potential. The data are,ˇrst, analyzed in terms of phenomenological potentials using the WoodsÄSaxon form for the real and imaginary parts supplemented by a spin-orbit potential of Thomas form. The analysis has been then performed using microscopic single folded complex potentials.
