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

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.
