Computer modeling was applied to the study of (n, alpha) transmutations in Si3N4 nanoparticles under the influence of neutrons at different energies. The modeling was separately performed for each Si and N atoms in the Si3N4 nanoparticles and the effect of neutrons on transmutations was investigated. The simulations were conducted individually for each stable isotope due to different effective cross-section of the probability of transmutation in the different types of isotopes of silicon and nitrogen atoms. Effective cross-section spectra of (n, alpha) transmutation in Si and N atoms were comparatively studied.
