Abstract

The probable α-accompanied cold ternary fission fragments of 257Fm are studied using six types of nuclear proximity potentials. We have studied the driving potential, probability, relative yield and half-lives of possible alpha ternary fission fragments. It is clear from present study that the alpha accompanied cold ternary fission reactions of 257Fm having minimum driving potential, maximum fission yield and small fission half lives for 48Ca + 205Pt + 4He. Hence this combination is recognized as most probable alpha ternary fission fragments of 257Fm due to the presence of doubly magic nucleus 48Ca. This study finds important in the experiments on alpha ternary fission of 257Fm.
