摘要

Abstract

This study presents the production cross sections of \({}^{232,230}\) Pa resulting from proton irradiationof \({}^{232}\) Th at an energy of 20.9 MeV. In addition, theexcitation functions of \({}^{233}\) Pa and \({}^{231}\) Th produced viaproton-induced reactions on \({}^{232}\) Th in the energy range from0.02 to 1.6 GeV are analyzed, with consideration of the possiblecontribution of secondary neutrons to their formation. Theproduction cross sections for all reaction products were measuredusing direct gamma-ray spectrometry without chemical separation.The obtained experimental data are compared with results reportedby other authors, as well as with calculated excitation functionsgenerated using the PHITS-3.31 code (INCL4.6/GEM, JAM, and Bertinimodels) and the TENDL-2023 nuclear data library.
