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.
