³⁴Si accompanied ternary fission of ²⁴²Cm in equatorial and collinear configuration

Abstract

Taking the interacting potential as the sum of Coulomb and proximity potential, 34 Si accompanied cold ternary fission of 242 Cm has been studied with fragments in the equatorial and collinear configuration. The cold valley plots (plot of driving potential versus mass number of fragments) and the calculations on the yields for the charge minimized fragments have been used to obtain the favorable fragment combinations. Thus, our study on the 34 Si accompanied ternary fission of 242 Cm reveals the role of near doubly magic shell closures (of 130 Sn, 132 Te, 134 Te, etc.) in cold ternary fission. The comparison of relative yield reveals that in 34 Si accompanied ternary fission of 242 Cm, collinear configuration is preferred than the equatorial configuration. The relative yield for binary exit channel is found to be higher than that of ternary fragmentation (both equatorial and collinear configuration). The predicted yield for the binary fragmentation of 4 He and 34 Si from 242 Cm are in agreement with the experimental data.

“…The relative yield is calculated for all possible fragmentations and plotted as a function of fragment mass numbers A 1 and A 2 as shown in figure 3(c) In the 6 He accompanied ternary fission of 252 Cf isotope, the driving potential is calculated for all possible fragmentations and plotted as a function of fragment mass number A 1 as shown in figure 2(d). Here the deepest minimum is found for the fragment combination 4 He+ 6 He+ 242…”

“…A number of theoretical and experimental works have been conducted in the field of ternary fission of various isotopes. We have developed a model named as Unified ternary fission model (UTFM) [2][3][4][5][6][7], in order to find the most favourable fragment combinations in the ternary fission process of various isotopes and our model is briefly described in the following section.…”
