Cross-sections of nuclear isomers in the interaction of protons on thin thorium target

摘要

The paper shows the results of experimental gamma spectra obtained from thorium²³²Th target, and an aluminum collector irradiated with protons at JINR Synchrocyclotron at energies of 100 and 660 MeV. For²³²Th, 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 the²³²Th and Al nuclei under the interaction of protons 100 and 660 MeV was determined. A comparison of the obtained cross sections of the reaction with theoretical calculations was made.
