A new study on pre-equilibrium and equilibrium effects of excitation functions of alpha-induced reactions on 51V, 55Mn and 59Co nuclei

In this article, the cross section simulations of ⁵¹V(α,n)⁵⁴Mn, ⁵⁵Mn(α,n)⁵⁸Co, ⁵⁵Mn(α,2n)⁵⁷Co, ⁵⁹Co(α,2n)⁶¹Cu and ⁵⁹Co(α,α2n)⁵⁷Co 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 n₀  = 5 appears to give a good harmony to the measured values.

Modelling study on production cross sections of 111In radioisotopes used in nuclear medicine

Radiopharmaceuticals are radioactive drugs used for diagnosis or treatment in a tracer quantity with no pharmacological action. The production of radiopharmaceuticals is carried out in the special research centers generally using by the cyclotron systems. Indium-111 is one of the most useful radioisotopes used in nuclear medicine. In this paper, we calculated the production cross sections of 111In radioisotope via 111–114Cd(p,xn) nuclear reactions up to 60 MeV energy. In the model calculations, ALICE/ASH, TALYS 1.6 and EMPIRE 3.2 Malta nuclear reaction code systems were used. The model calculation results were compared to the experimental literature data and TENDL-2014 (TALYS-based) data.

A study on empirical systematic for the (d,n) reaction cross sections at 8.6 MeV

Recently, many formalizations have been developed to explain some reaction mechanisms such as neutron or proton induced reactions. In this study, (d, n) reaction mechanism was investigated developing the cross-section systematic formula. The (d, n) cross sections at 8.6 MeV deuteron energy have been calculated using these formula for some target nuclei (A = 10∼123). The cross sections calculated are important for the development of fusion reactor technology. Obtained calculation results from the formula have been also compared and discussed with results calculated by the codes ALICE/ASH (equilibrium and pre-equilibrium theories) and TENDL-2012 (Talys-based), and with results of available experimental values. It is shown, that the suggested empirical equation at the 8.6 MeV deuteron energy works very well for a quick estimation of (d, n) nuclear cross sections.
