Investigating the excitation functions of the neutron-induced reactions leading to the radioactive products on natural titanium isotopes

Abstract

In this study, the excitation functions of some (n, x) reactions leading to the radioisotope products on natural titanium isotopes, which is an important material for fusion technology, are calculated by using the ALICE/ASH and TALYS 1.95 codes. Besides, the effects of the phenomenological and the microscopic nuclear level density models on these excitation functions are investigated by using the two-component exciton and geometry dependent hybrid models. The obtained results for the considered reactions in this study are compared with the available experimental and ENDF/B-VIII data, and the suitable nuclear level density model is determined for each reaction. According to the results, the phenomenological nuclear level density models are generally in good agreement with experimental data, except for 48Ti(n,d) and 50Ti(n,γ) reactions. Also, the results of this study can be used to predetermine radiotoxicity in the structural material for a fusion reactor.
