Cross section calculation of 239Pu, 233U and 234U nucleus gamma-fission between 0-20 MeV

In this study, cross section of 239Pu, 233U and 234U have been calculated. TALYS 1.2 computer program was used for calculations. Calculations have been studied by 0-20 MeV incident energy gamma. In TALYS 1.2 calculations, all sistematics of fission barrier parameters (Experimental Fission Barriers, Theoretical Fission Bariers Mamdouh Table, Theoretical Fission Bariers Sierk Model, Theoretical Fission Bariers Rotating Liquid Drop, WKB Approximation for Fission Path Model) and shell model parameters (Myers ? Swiatecki Model, Goriely Model) was used for each of nuclei. Experimental datas, taken from Experimental Nuclear Reaction Data (EXFOR) www-nds.iaea.org/exfor/ address is compared on graphic. For nuclei, different theorical values are compared and investigated with experimental values.
