Abstract

The interaction of high energy alpha particles with atomic nuclei is considered using multiple scattering theories. Semi-classical solutions to coupled-channel equations derived from Watson's form of the nucleus-nucleus multiple scattering series are shown to be equivalent to the Glauber multiple scattering series. Second-order solutions for the elastic amplitude are developed and used to study the effects of short-range correlations in nuclear scattering. The Jastrow method is used to model the two-particle density for 4He and to construct one and two particle form factors. Excellent agreement with experimental data for angular distributions, and total and reaction cross sections is found. The inclusive momentum distribution for projectile fragmentation is developed in terms of Lorentz invariant three-particle phase space. The participant-spectator description of the fragmentation of alpha particles is formulated using direct reaction theory. Overlap functions for the virtual dissociation of alpha particles are considered.
