Coupled-Channel and Distorted-Wave Born Approximation Analyses for 25.1 MeV and 32.5 MeV Energies of p-40Ar Inelastic Scattering

Abstract

The optical model parameters, the coupled-channel parameters and excitation mode β<inf>2</inf> , β<inf>3</inf> and β<inf>5</inf> deformation parameters corresponding to the best fit to the experimental differential cross-sections and the analyzing powers data for the p- 40Ar elastic and inelastic scattering were determined. The ambiguity in the spin and parity of the 4.43±0.05 MeV state of 40Ar was solved by the assignment of the 5- value for this state. Also, for the 40Ar nucleus a first-degree vibrational model was found to be suitable. © 2008 Società Italiana di Fisica and Springer-Verlag.
