Theoretical calculations of production cross–sections for the 201Pb, 111In 18F and 11C radioisotopes at proton induced reactions

Abstract

Production of radioisotopes that used in medical diagnosis and treatment are mostly based on the nuclear reactions. The cross–section data are important to understand nuclear reaction mechanisms. In this study TALYS 1.8 code has been used to calculate production cross–sections of 201Pb, 111In, 18F and 11C radioisotopes at proton induced reactions. Constant Temperature Fermi Gas Model (CTFGM), Back Shifted Fermi Gas Model (BSFGM) and Generalised Super Fluid Model (GSM) have been employed as a level density models for computations. Relative variance calculations have been carried out to determine the best level density model. In addition to cross–section calculations, total activities of radioisotopes have been presented. Production cross–section calculation results have been compared with experimental data taken from Experimental Nuclear Reaction Database (EXFOR).
