Nuclear Model Calculations on the Excitation Functions of Some Radionuclides Produced by Proton Cyclotron

By using the intermediate energetic proton induced reactions, we can produce radionuclides and these radionuclides can be used in medicine and industry. In the last decade, a big success has been provided usage of radionuclides. Nuclear reaction calculations which are based on standard nuclear reaction models can be helpful for determining the accuracy of various parameters of nuclear models and experimental measurements. In this study, production routes of medical isotopes used for diagnostic or a therapeutic radionuclide such as 225Ac, 140Nd, 43Sc and 44Ti were investigated in a range of 10–50 MeV incident proton energy. The excitation functions for (p,2n) reactions were calculated by equilibrium and pre-equilibrium reaction mechanisms. The pre-equilibrium calculations were calculated by using hybrid, geometry dependent hybrid and cascade exciton model. The reaction equilibrium component was calculated with a traditional compound nucleus model developed by Weisskopf-Ewing. Calculation results have been also compared with the available measurements in literature
