Analysis of elastic and inelastic α- 12C data ( Eα = 1.37 GeV) with a multiple diffraction model

Abstract

High-energy inelastic α- 12C distributions are analyzed with an eikonalized DWIA. Using an elastic phase function parametrized to fit the elastic α- 12C distribution and further inelastic form factors from electron scattering data, we obtained reasonable agreement for the 2 + and 0 + distributions. We observe and discuss the anomalous absence of a predicted diffraction minimum in the 3 − distribution as is also the case for the 1 GeV p- 12C data.
