Abstract

The cold ternary fission of ²⁴²Cm with ⁴He , ¹⁰Be and ¹⁴C as light charged particle has been studied by taking the interacting barrier as the sum of Coulomb and proximity potential with the fragments in equatorial configuration. The favorable fragment combinations are obtained from the cold valley plot (plot of driving potential vs. mass number of fragments) and by calculating the yield for charge minimized fragments. The maximum yield in the ⁴He accompanied ternary fission is obtained for the fragmentation channel ¹⁰⁴Mo + ¹³⁴Te + ⁴He and for the ¹⁰Be accompanied ternary fission, the maximum yield is found for the fragmentation channel ⁹⁸Zr + ¹³⁴Te + ¹⁰Be . It is to be noted that, in the case of ¹⁴C accompanied ternary fission, the maximum yield is obtained for the fragmentation channel ⁹⁴Sr + ¹³⁴Te + ¹⁴C and the next higher yield is found for the fragmentation channel ⁹⁶Zr + ¹³²Sn + ¹⁴C . Thus, the fragment combinations with maximum yields reveal the role of doubly magic and near doubly magic nuclei in cold ternary fission.
