A Study of The Alpha – Nucleus Scattering

Angular distribution data for the elastic scattering of 1.37 GeV alpha particles from several nuclei are analyzed in terms of the three parameter strong absorption model of Frahn and Venter. The fits are quite satisfactory over practically the entire angular range and the best fit parameters are obtained. These are used for the study of the inelastic scattering of alpha particles leading to the collective states in nuclei. A reasonably good fit is obtained without any adjustment of the parameters suggesting thereby the success of the strong absorption model. Deformation parameters are extracted for the collective states in nuclei. Asiat. Soc. Bangladesh, Sci. 40(2): 249-258, December 2014

Nucleus Scattering

Angular distribution data on the elastic scattering of pions are studied on several nuclei around the Δ resonance in terms of the three-parameter strong absorption model of Frahn and Venter. The parameters thus obtained are used in the analyses of inelastic scattering of pions leading to the lowest as well as higher lying 2+ and 3- states, and the corresponding deformation parameters are extracted.

Best Fit

The angular distribution data for the elastic scattering of 100–172.5 MeV isoscalar alpha particles from several nuclei between 16 O and 208 Pb are studied within the framework of the strong absorption model due to Frahn and Venter. The best fit parameter values of the nuclear interaction are determined. These are then used to analyze the inelastic scattering of alpha particles leading to the excitation of the 2+ and 3- collective states in the target nuclei and the corresponding deformation parameters are extracted. A reasonably good account of both elastic and inelastic scattering is given by the same set of parameter values derived from the analyses of the elastic scattering.

High Temperature Approximation

The theory of the angular distribution of alpha particles and of fission fragments from nuclei aligned at low temperatures is presented. Very explicit results are obtained in the high temperature approximation. These are directly dependent upon the branching which takes place to the various allowed partial waves. This branching is influenced by the nuclear shape, but it is shown that for this problem the effect of penetrating a spheroidal barrier is not critical. An application is made to the experimental work so far available and the result is reasonably satisfactory.
