Tin-accompanied and true ternary fission of ²⁴²Pu

Abstract

True ternary fission and Tin-accompanied ternary fission of 242 Pu are studied by using 'Three Cluster Model '. True ternary fission is considered as formation of heavy fragments in the region 28 ≤ Z 1 , Z 2 , Z 3 ≤ 38, with comparable masses. The possible fission channels are predicted from potential-energy calculations. Interaction potentials, Q-values and relative yields for all possible fragmentations in equatorial and collinear configurations are calculated and compared to each other. It is found out that ternary fission with formation of a double magic nucleus like 132 Sn is more probable than the other fragmentations. Also the kinetic energies of the fragments for the group Z 1 = 32, Z 2 = 32 and Z 3 = 30 are calculated for all combinations in the collinear geometry, as a sequential decay.

Deformation parameter changes in fission mass yields within the systematic statistical scission-point model

“…The extremum values of energy at the scission point is usually used to find the atomic numbers of the fission fragments [36][37][38][39]. The exponential function is upward-sloping, so the minimum total energy at the scission point has the greatest effect in equation (2).…”
