10Be-accompanied ternary fission of Cf isotopes: a level density formulation

Abstract

10Be-accompanied ternary fission of Cf isotopes has been studied using the level density formulation. The fragment combinations are determined by minimizing the driving potential at the touching configurations of three fragments using deformed Coulomb and deformed proximity potential and the yield has been determined by the level density formulation. In addition to the usual procedure of taking the yield for fragmentations, which is proportional to the total level density at a particular temperature, calculations have also done with the assumption that the probability is proportional to total number of states in a range of energy. Three sets of calculations have been done by taking different ranges of temperatures and compared with the experimental data for 252Cf. On the basis of the agreement noticed, the calculations have been extended into all even mass isotopes of Cf and the major fragmentations involved in the 10Be-accompanied ternary fission of Cf isotopes have been predicted.
