Compound Particle-Core Coupled States and Direct Nuclear Processes

Abstract

We report a detailed study of the inelastic scattering reaction ${}_{}{}^{206}{}_{}{}^{}\mathrm{Pb}(p,p^{\prime }){}_{}{}^{206}{}_{}{}^{}\mathrm{Pb}_{}^{*}{}_{}{}^{}\left(2_1^{}{}_{}{}^{+}\right)$ for incident proton energies in the range from 14.2 to 17.3 MeV. It has been found possible to reproduce the experimental results quantitatively using a theoretical analysis incorporating a number of resonant compounds, as well as direct inelastic, scattering amplitudes. Interference effects play an important role and predictions of shell and weak-coupling models are found to be in excellent agreement with the experimental data.
