Inelastic proton scattering on excited states of 9Вe nucleus ( J   3 2 , 5/ 2 ) in the framework of glauber theory

Abstract

In the framework of Glauber diffraction theory a calculation of ifferential cross section for inelastic р9Ве-scattering has been carried out. The wave function of 9Ве nucleus for the ground and the excited states in the three-particle ++n-model was used. The expansion of the 9Ве nucleus wave function in a series by gaussterms and representation of the Glauber Ω operator in a form which conjugates to the three-particle wave function allow to calculate analytically the matrix elements of the inelastic scattering with account of all orders of scattering and re-scattering on clusters and nucleon composing the 9Ве nucleus. The maximum of the calculated differential cross section with the wave function in both models is close to the experimental maximum, however at θ > 35* with the wave function in the model 1 it ecreases faster than the experimental one, in the model 2 – slower. For comparison we bring forward the result of differential cross section calculation in the distorted wave approximation with the effective density-dependent interaction which is based on the Paris potential.
