ESTIMATION OF PARAMETERS IN NUCLEAR MODEL FORMULA FOR NUCLIDES OF STRUCTURAL MATERIALSDepartment of Energy Conversion Engineering, Kyushu University, Kasuga, Fukuoka 816, Japan Optical model parameters and level density parameters for Hauser-Feshbach model calculations have been estimated systematically for Z = 22 to 28 nuclei by using Bayesian method. The experimental data for the estimation are total, (n,p), (n,α), and (n,2n) cross sections, and energy distribution of proton and α-particles emitted by neutron induced reactions. The prior optical model parameters of neutron, proton, and α-particles are taken from Beccetti-Greenlees', Menet et al.'s, and Huizenga-Igo's values, respectively. The prior level density parameters are taken from Gilbert-Cameron's values. The optical model and level density parameters estimated in the present work have been found to be reasonable comparing with the other works. The cross sections calculated with posterior parameters have been improved more than those done with prior ones.
