Abstract

Experimental fission data for nuclei in the mass regionA = 210 toA =258 are discussed from a unified point of view using cluster representations of nuclei. It is shown that these data can be described as resulting from a superposition of two different modes, one determined by energetically favoured cluster correlations, the other due to liquid-drop effects only. For all nuclei lighter than Fermium the above distinction coincides with that of symmetric and asymmetric fission. Contrary to that in Fermium-isotopes, both symmetric and asymmetric fission are associated with energetically favoured cluster correlations at the Fermi surface.
