Level density model effects on the production cross-section calculations of some medical isotopes via (α, xn) reactions where x = 1–3

Abstract

Level density models have an undeniable importance for a better perception on the na- ture of nuclear reactions, which influences our life via various ways. Many novel and advanced medical application use radioisotopes, which are produced with nuclear re- actions. By considering the connection between the level density models and the im- portance of theoretical calculations for the production routes of medically important isotopes, this study is performed to investigate the level density model effects on the production cross-section calculations of 62Zn, 68Ga, 77Kr, 103Pd, 111In, 124I and 211At radioisotopes via some alpha particle induced and neutron emitting reactions. For the- oretical calculations; frequently used computation tools, such as TALYS and EMPIRE codes, are applied. Obtained theoretical results are then compared with the experimental data, taken from Experimental Nuclear Reaction Data (EXFOR) library. For a better interpretation of the results, a mean weighted deviation calculation for each investigated reaction is performed in addition to a visual comparison of the graphical representations of the outcomes.
