Abstract

The paper shows the results of experimental gamma spectra obtained with a thorium ²³²Th target and an aluminum collector irradiated at the JINR Synchrocyclotron with the internal beam of energies of 100 and 600 MeV. For ²³²Th there were identified 258 and 222 gamma lines that belong to 45 and 55 nuclides, respectively. For Al - 238, 330 lines and 81, 119 nuclides, respectively. The cross sections of fragmentation of the ²³²Th and Al nuclei under the interaction with protons 100 and 600 MeV was determined. A comparison of the obtained cross sections of the reaction with theoretical calculations was performed.
