Show affiliationsThe multimode fission model is examined from the systematics of empirical data and the potential-energy surface near the scission point. Primary mass distributions of fissioning systems, from Ac to Fm with various excitation energies, are analysed. It is found that all the distributions can be well approximated by a superposition of five Gaussian function with parameters varying smoothly with the mass and excitation energy of the fissioning systems. The success of this analysis is clear indication of the general existence of three main modes of fission in the studied range. The difference between the empirical data and the calculated mass distributions gives a clear indication of the odd-even effect of the fragment charge distribution. There may also be other minor modes, different for different fissioning systems.
