Summary:Abstract New results demonstrating the so-called Ni-bump being the most populated mode of the collinear cluster tripartition (CCT) of 252 Cf(sf) are presented. The physical scenario of this effect is discussed. It is tested by calculations of potential energy surfaces for the fission of the intermediate fragments formed after first rupture of the mother nucleus. Fission barriers are extracted and mass asymmetries at saddles are compared with the masses of the fission fragments that take part in the Ni-bump.
