Abstract

The most possible alpha-accompanied ternary fission fragment of 217-219Ac are studied using Coulomb and proximity potential model. We have studied driving potential (V-Q), logarithmic half-lives and relative yield of all possible fission fragments. From the present work, the minimum driving potential, maximum relative yield and minimum half-lives are observed for the fragment combination of 4He+209-211Ac+4He for the nuclei 217-219Ac. Hence, this fission fragment combination is considered as most possible fission fragments due to presence of doubly magic nuclei. This study is important in near future experiments.
