The library of the GEANT4 classes and the G403700100021 low-energy electromagnetic processes models EPDL97 G403700100022 and EEDL97 were used. G403700100023 SAMPLE The chemical substances, which contained the given G403700100024 elements, were as follows: boron nitride (BN), G403700100025 aluminum nitride (AlN), corundum (Al2O3), and G403700100026 pyrographite (C). Target mass:C-0.91g, N-0.3g, O-0.48g.G403700100027 DETECTOR (GE)The spectrometer complex "CANBERRA InSpector-2000" G403700100028 with a sufficient energy resolution of not less G403700100029 than 1.74 keV in the region of 1332 keV.
