N2 - The 180 MeV p+27Al reaction is investigated using antisymmetrized molecular dynamics, i.e., AMD and AMD-V, to investigate properties of fragment formations in medium energy nucleon-induced reactions. After statistical decay calculations, both AMD and AMD-V almost reproduce experimental mass distributions, differential, and double differential spectra of fragments in the p+27Al reaction. However, the inclusion of the diffusion and the deformation of wave packets in AMD-V has drastic effects and, then, aspects in dynamical calculations of AMD-V are very different from AMD calculations. It is shown that various aspects of nucleon-induced reactions, in which residual nuclei decay into several fragments, appear in AMD-V calculations. The decay into fragments proceeds slowly, and thus, differs from the multiple fragmentation in heavy ion collisions. The possibility that AMD-V dynamical calculations describe the processes of statistical decays is discussed.
