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