Up to the highest momentum transfer measured [≃2 (GeV/c${)}^2$], the inelastic double differential α-nucleus cross sections obtained with α’s of 7 GeV/c incident momentum are fairly well described by an incoherent sum of single and double quasielastic collisions on the substructures of the target, and the different orders of scattering are clearly identified. The assumptions used in this analysis are also justified by the elastic behavior of the integrated partial cross sections that correspond to these different orders of scattering. The interpretation of these integrated cross sections by a Glauber model enables the evaluation of the mean square radii as well as the spectroscopic factors of the substructures concerned. Pion processes measured in these α-nucleus collisions are also considered.
