We simulate the fragmentation processes in the {$\alpha$~$+$~Au~} collisionsat a bombarding energy of 5 GeV/u using the simplified RQMD approach plus thestatistical decay model. We find from the simulation that theangular-distribution of the intermediate mass fragments has a sideward peak,more strongly in the transverse direction than in the beam-direction, when theintermediate nucleus formed by the dynamical process has an annular eclipseshape, which explains the experimental results.Comment: 11pages, Rectex is used, 3 Color-Postscript figures are also available by request from tomo@hadron05.tokai.jaeri.go.j
