Abstract

The binary fission of superheavy nuclei 299121 and fission fragments is studied using Coulomb and proximity potential model. The total potential is evaluated using the recent proximity potential model. The total potential is evaluated for different fission fragment combinations. The probable fission fragment combination has been obtained using a cold valley plot. The identified favourable fission fragments are found to be 139La+160-166Gd with the half-life in the order less than zeptoseconds. The role of symmetric or asymmetric fission fragments were analysed. The binary fission fragment combination 139La+160Gd with maximum yield and smaller half-lives in which the fission fragment 139La will have magic neutron number with N=82.
