摘要
Potential energy surfaces corresponding to the alpha accompanied ternary fragmentation in superheavy mass region have been investigated. The lowest value of potential energy is found for the configuration having alpha particle in between other two fragments. The position of deepest valleys in the potential energy surface indicates the most probable tri-partition of a given nucleus. The isotopic effect on the variation of the deepest valley has also been investigated. For the isotopic chain of Z = 114, the minimum is found at Ce-140 + He-4 + Xe-136, suggesting this to be the most probable tri-partition. Similar possible configurations have been studied for Z = 116, 118 and 120 and the presence of proton/neutron magic number has been found in all the most probable combinations for alpha accompanied ternary fission.
