Properties of the (α,α*) Reaction at Very Forward Angles: Coupled-Channels Effects in Single and Mutual Excitation

Abstract

possibly could be explained by invoking a prompt mechanism, we feel that one should not ignore the well-known evaporation process, which is certain to be present. In fact, we have shown that evaporation in the presence of thermal fluctuations in the division of the excitation energy could reproduce the high-energy protons associated with the deep-inelastic channel.

β-band excitation in inelastic hadron scattering and the mixing of the breathing mode into the low-lying β-vibrations

“…In fact, strong channel coupling can affect the differential cross sections for various channels drastically. Such ef-fects have been observed [9], for example, in single and mutual excitation of a-scattering from 24Mg and 28Si. Moreover, attempts to fit the experimental 40 + MeV [10] and 20 MeV [11] (p, p') data for the 0/3 state of 24Mg with DWBA calculations using either macroscopic [ 10] (vibrating-diffuseness and breathing mode) form factors or microscopic [10,11 ] form factors failed.…”
