Technique of selective registration of Mössbauer spectra from recoil atoms formed in nuclear reactions /1/ was used for investigations of local damaged zones in amorphous Fe70Ni10P13C7 alloy irradiated by high-energy charged particles — 30 MeV protons and 50 MeV alpha-particles — up to doses of 1022 m−2. From absorption spectra of the alloy before and after irradiation and emission spectra conclusions are made about a state of the alloy damaged zones nearby the stopped57Co atoms formed in nuclear reactions. It is established that in the irradiated amorphous samples57Co atoms are stabilized in γ-phase and iron carbides and phosphides, and crystallic phase of α-Fe is formed far enough from them. In the crystallic samples no amorphization or any other transitions take place.
