A new study on pre-equilibrium and equilibrium effects of excitation functions of alpha-induced reactions on V, Mn and Co nuclei.

In this article, the cross section simulations of V(α,n)Mn, Mn(α,n)Co, Mn(α,2n)Co, Co(α,2n)Cu and Co(α,α2n)Co nuclear reactions were carried out using the pre-equilibrium and equilibrium models. TALYS 1.9 and ALICE/ASH codes for the above nuclear reactions were used to describe the formation of the reaction process. Besides, the contribution on the cross section calculations of initial exciton number for alpha-induced reactions at the pre-equilibrium emissions is discussed. The results of this paper are compared with the measured nuclear data found in the literature. It was found that the initial exciton number n  = 5 appears to give a good harmony to the measured values.
