Investigation of Sub-Coulomb barrier fusion reaction of α +40Ca in different models

In this study, microscopic nucleon–nucleon Double Folding (DF) and phenomenological potentials have been used to investigate [Formula: see text]Ca reaction observables at sub-barrier energies. In the calculations, semi-classical Wentzel–Kramers–Brillouin (WKB) approach has been used in order to obtain the cross-sections and reaction rates of [Formula: see text]Ca. Besides WKB approximation, we have also utilized Talys code in order to get the comparative results and find out the method differences. To estimate the reaction rates, energy-dependent cross-sections and astrophysical S-factors of [Formula: see text]+[Formula: see text]Ca have been used. Herewith, differences between models and potentials have been demonstrated using the reaction rate estimates.

Implementation of New Fission Barrier Model in TALYS Code

This paper is aimed to calculate neutron induced fission cross section using TALYS nuclear reaction code by utilizing new fission barrier model parameter. The new fission barrier model is based on minimization method of action functional of deformed nucleus fission trajectory in configuration of space from ground state to the exit barrier. New fission barrier parameter that obtained from this new model will be fed into the TALYS code to calculate the fission cross section of Th-232 and U-238 through statistical method. The result shows a better agreement with ENDF data compared to that of ETFSI (Extended Thomas-Fermi and Strutinsky Integral) or Mamdouh model of fission barrier for energy between 2 and 10 MeV.
