Description
Summary:Results are presented for pulse amplitude spectra of crystals based on complex oxides irradiated in mixed fields of neutron and gamma-radiation. These crystals-CdWO/sub 4/ (CWO), Gd/sub 2/Si/sub 2/O/sub 5/(Ce) (GSO(Ce)) and NaBi(WO/sub 4/)/sub 2/-include elements with large radiation capture section of thermal and resonance neutrons. It has been shown that it is possible in principle to separately detect products of nuclear reactions of radiation capture of neutrons on Cd, W, Gd and Na nuclei. This is realized by the appropriate choice of energy windows during detection of nuclear reaction products and the accompanying gamma-radiation using scintillators with different decay times and different interaction cross-sections, as well as with the help of screens selectively absorbing neutrons or gamma-quanta.
