A study on light charged particle accompanied ternary fission of 253Cf

We investigated 253Cf ternary fission followed by a light-charged particle (LCP) accompanied ternary fission. The many LCPs, include 4He, 6Li, 9Be 10B, 12C, 14N, 16O, 19F 20Ne, 23Na 24Mg, 26Al, 28Si, 30P 32S, 35Cl, 40Ar, 39K and 40Ca. Using Coulomb potential and proximity potential, the overall pote...

Description
Summary:	We investigated 253Cf ternary fission followed by a light-charged particle (LCP) accompanied ternary fission. The many LCPs, include 4He, 6Li, 9Be 10B, 12C, 14N, 16O, 19F 20Ne, 23Na 24Mg, 26Al, 28Si, 30P 32S, 35Cl, 40Ar, 39K and 40Ca. Using Coulomb potential and proximity potential, the overall potential has been investigated. In estimating potential, deformations and angle of orientation were taken into account. Using cold valley plots, the driving potential at its lowest level is determined. Using WKB integral, the penetration probability is evaluated. When the fission fragment combinations include equal or close to the magic number of protons or neutrons, the minimal driving potential, maximum penetration probability, and maximum logT1/2 are observed. Therefore, 138Ba+4He+111Ru are the most likely fission fragment combination when 253Cf undergoes LCP followed ternary fission. Therefore, 4He particle-emission coupled with two likely fission fragments are the most likely fission fragments if the nuclei 253Cf undergo LCP-accompanied ternary fission. The significance of this finding may thus be seen in the ternary fission half-lives.
