Implementation of LSD Fission Barrier in Fission Cross Section Calculations

Abstract

Abstract In this paper, the fission cross-sections of Th-232(n, f) and U-238(n, f) have been calculated using the fission barrier parameter obtained from Lublin-Strassbourg Drop Model (LSD) in the statistical model framework. This model has been derived from the modern liquid drop (NLD) by adding a first-order curvature term that depends on the deformation parameter. This term has resulted from the implementation of Leptodermous expansion of nuclear energy. The deformation function involved in LSD formulation is obtained from Funny Hills nuclear shape parameterization. The obtained results would be compared with another result calculated using ETFSI (Extended Thomas Fermi and Strutinsky Integral) method and experimental fission cross-section extracted from ENDF data.
