Investigation of Ternary Fission of (98) (252) Cf Using Three-Cluster and Unified Ternary Fission Models

摘要

Using three-cluster and unified ternary fission models, the ternary fission of (98) Cf-252 is studied. We applied collinear and equatorial configurations to study the ternary fission of (98) Cf-252 when the third fragment is (3) Li-10. The nuclear potential energy in the three-cluster model and unified ternary fission model is calculated respectively, using Yukawa plus exponential and proximity formalisms. The relative yields of different fragmentation channels are calculated. Our results reveal that the ternary fragmentation potential of the three fragments and the relative yields depend on the configuration of three fragments and usedmodel. Two models predict that the lowest driving potential and highest relative yield take place for the fragment combination (51) Sb-132 + (44) Ru-110 + (3) Li-10. Also, the values of driving potential and relative yield are not equal in the three-clustermodel and unified ternary fission model. For fragment combination (51) Sb-132 + (44) Ru-110 + (3) Li-10, the relative yield based on the three-cluster model in collinear configuration is maximum, whereas the unified ternary fission model in equatorial configuration predicts the lowest relative yield.
