Abstract

The 600 MeV proton-induced fission process of Ce and Yb has been investigated with the double-kinetic-energy method. Mass distributions of these and other medium-heavy and light nuclei are compared to predictions of macroscopic models. No sign of the Businaro-Gallone point, below which the saddle point becomes unstable towards mass asymmetric deformations, is observed. For Ce a stable asymmetric mass distribution is found which may be explained in terms of shell structure effects.
