Abstract: Photofission cross-sections of ^{238,239,240,241,242,244}Pu isotopes are theoretically investigated with the collective semi-classical Fermi gas model (CSCFGM) by using Talys computer code in the energy range 1 - 30 MeV. Nuclear level density has significant importance to define the structural properties of nuclei. CSCFGM is a nuclear level density model, that includes collective (rotational and vibrational) effects as well as the pairing and shell effects, and is used to analyse the (γ, f) reactions of plutonium isotopes. The experimental data for all reactions are taken from EXFOR library. The theoretical predictions are in agreement with the experimental data, Talys code without changing the input, and the evaluated nuclear cross-section data from TENDL 2021 library.

Keywords: photofission reaction, Talys, nuclear level density, plutonium isotopes.
