Abstract

Pioneering study reveals that a radioactive nucleus may split into two or three fragments and the phenomena are known as binary fission and ternary fission respectively. In order to understand the nuclear stability and related structure aspects, it is of huge interest to explore the fragmentation behavior of a radioactive nucleus in binary and ternary decay modes. In view of this, Binary and ternary fission analysis of 252Cf nucleus is carried out using quantum mechanical fragmentation theory (QMFT). The nuclear potential and Coulomb potential are estimated using different versions of radius vector. The fragmentation structure is found to be independent to the choice of fragment radius for binary as wellas ternary decay paths. The deformation effect is included up to quadrupole (β2) with optimum cold orientations and their influence is explored within binary splitting mode. Moreover, the most probable fission channels explore the role of magic shell effects in binary and ternary fission modes.

Highlights

Radioactivity is one of the prominent branch of the nuclear physics, which provides opportunity to understand the inter-nuclear forces and related structural aspects
The geometrical mode where the third fragment emission happens orthogonal to fission axis is known as equatorial mode and when the emission of third fragment happens along the fission axis it is termed as collinear decay mode
P.57 a particular decay channel with respect to other probable modes. It can be noted from the figure that there is no change in the fragmentation structure with change in the radii expression, but we find significant difference in the magnitude of the fragmentation potential

Summary

Introduction

Radioactivity is one of the prominent branch of the nuclear physics, which provides opportunity to understand the inter-nuclear forces and related structural aspects. Beside the abovementioned binary decay modes, a radioactive parent nucleus may proceed via simultaneous emission of three fragments. This kind of splitting mode is known as the ternary fission. A theoretical analysis of related aspects is carried out by taking 48Ca as the third fragment by using three cluster model (TCM) [4] and probable decay path is explored using three body penetration profile [1]. Present work aims to analyze the role of inter-fragment radius in binary and ternary decay path of 252Cf radioactive nucleus
