The absorption of neutrons in nano-Si3N4 particles at different energies has been studied by computer modeling. The investigation was carried out separately for the silicon and nitrogen atoms that contain Si3N4 nanoparticles. Since the effective cross-section of absorption in different types of isotopes of silicon and nitrogen atoms is different, the modeling was performed separately for each stable isotope. Simultaneously, the effective cross-section spectra of neutrons for silicon and nitrogen atoms were studied.
