Correlations in alpha-alpha scattering and semi-classical optical models.
We show the equivalence of semi-classical solutions to optical model coupled-channel equations derived from Watson's form of the nucleus-nucleus multiple-scattering series to the Glauber multiple-scattering series.  A second-order solution to the semi-classical coupled-channel elastic amplitude is shown to be nearly equivalent to a second-order optical-phase-shift approximation to the Glauber amplitude if the densities of all nuclear excited states are approximated by the ground-state density.  Using the Jastrow method to model the two-body density we find an average excited-state density to be of negligible importance in the double-scattering  region of alpha-alpha scattering.
