Abstract

Elastic and inelastic scattering of unpolarized and polarized protons by Ar-40 nuclei for incident energies between 20 and 50 MeV has been studied by reanalyzing experimental scattering spectra for the 2(+)(1.46 MeV) and 3(-)(3.68 MeV) levels in the angular range 30 degrees-160 degrees for incident protons of energies of 25.1, 32.5, and 40.7 MeV. An isospin dependent soft-rotator coupled-channels optical model with the potential containing a dispersive term with a nonlocal contribution is used to analyze the data.
