The Search for Target Structure Effects in Elastic Scattering

In elastic scattering, the question occurs as to how to separate details of the target structure from those of the projectile when using both standard optical potentials and semi-microscopic potentials in detailed coupled channels calculations. We will show that by graphing the cross section and analyzing power data as a function of momentum transfer rather than scattering angle that it is possible see regions of momentum transfer where effects arise from the projectile alone and regions where the target contribution must be accounted for. For light mass systems, these effects are more easily observed in the data by plotting the scattering cross section with respect to momentum transfer rather than the normally used ratio to Rutherford. The analysis of data for the elastic scattering of polarized $^{7}$Li from targets of $^{6}$Li, $^{7}$Li and $^{12}$C will be presented. A similar analysis of previously published data for $^{6}$He (1) and $^{6}$Li (2) elastic scattering from $^ {12}$C will also be presented.\\ (1) V. Lapoux et al. Phys. Rev.
