Shevchenko O. Excitation of isomers 113mIn, 115mIn, 111mCd, 117mSn, 87mSr in (g ,g' )m reaction at the energy g -rays below 3 MeV

The thesis is devoted to the investigation of nuclear isomers excitation in the inelastic gamma scattering reactions. Experiment was done with activation technique. The samples of natural indium, cadmium, tin, strontium were irradiated by bremsstrahlung beams from electron electrostatic accelerator ELIAS up to 3 MeV. Targets activity were detected by Ge (Li) g-spectrometer, with a working volume 40 cm3 and energy resolution 2.5 keV for g-line1332 keV of 60Co. The yield of 115In(g,g')115mIn, 113In(g,g')113mIn, 111Cd(g,g')111mCd, 117Sn(g,g')117mSn, 87Sr(g,g')87mSr reaction were measured. The integral cross sections of nuclei activation states of 113mIn, 115mIn, 111mCd, 117mSn, 87mSr were measued. The results which received in this work are compared with other works and theoretical calculations results.
