Abstract

The elastic scattering differential cross section is calculated for proton scattering from 6He at 717 MeV, using single scattering terms of the multiple scattering expansion of the total transition amplitude (MST). We analyse the effects of different scattering frameworks, specifically the Factorized Impulse Approximation (FIA) and the Fixed Scatterer (adiabatic) Approximation (FSA) and the uncertainties associated with the use different structure models.
