. The cold ternary fission of 242 Cm with 4 He , 10 Be and 14 C 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 4 He accompanied ternary fission is obtained for the fragmentation channel 104 Mo + 134 Te + 4 He and for the 10 Be accompanied ternary fission, the maximum yield is found for the fragmentation channel 98 Zr + 134 Te + 10 Be . It is to be noted that, in the case of 14 C accompanied ternary fission, the maximum yield is obtained for the fragmentation channel 94 Sr + 134 Te + 14 C and the next higher yield is found for the fragmentation channel 96 Zr + 132 Sn + 14 C . Thus, the fragment combinations with maximum yields reveal the role of doubly magic and near doubly magic nuclei in cold ternary fission.
