Abstract
Inelastic alpha particle scatterings to selected states in24Mg,28Si and40Ca are analysed. The transitions, all of which display anomalous structure in their differential cross sections at large scattering angles, are weakly, if at all, promoted by normal first order inelastic scattering reaction processes. To explain the anomalous structure, we utilize a two step reaction model in which the intermediate states are quasi-molecular. The energy variation of large angle scattering data shows that the quasi molecular intermediate states form a rotational band identical to that required to explain anomalous structure in the angular distributions of elastically scattered alpha particles.
