Cross-Sections Of Nuclear Isomers In The Interaction Of Protons On Thin Thorium Target

Abstract

The paper shows the results of experimental gamma spectra obtained with thorium 232Th target, and an aluminum collector irradiation with protons at an energy JINR Synchrocyclotron 100 and 660 MeV. For Th232, identified 258 and 222 gamma lines that belong to 45 and 55 nuclides. For Al - 238, 330 lines and 81, 119 nuclides respectively. The cross sections of fragmentation of the 232Th and Al nuclei under the interaction of protons 100 and 660 MeV were determined. A comparison of the obtained cross sections of the reaction with theoretical calculations was made.
