Abstract The binary fission process in Bi, Au, W, Sb, Ag and Ni induced by 1 GeV protons has been investigated. The energies, time-of-flight and angular correlations of coincident fragments were measured by using a double arm spectrometer permitting a direct mass determination. Mass distributions are found to change their shape for nuclei lighterW. The interaction of protons with nuclei followed by fission is described in the framework of the cascade-evaporation model and the statistical approach. The observed mass distributions are in a good agreement with the results of the calculation. The experimental results present evidence for existence of an instability region with respect to the mass asymmetry coordinate in nuclear fission.
