Abstract

Internal radiation effects of the57Ni→57Co→57Fe double decay are investigated by means of57Fe Mössbauer emission spectroscopy in57Ni-labelled metallic nickel. The recoil of57Co atoms due to neutrino and high-energy γ-ray emission has been detected at low temperature. According to the replacement collision mechanism, recoil atoms are located in two different vacancy-associated substitutional positions. The experimental results and the subsequently proposed recoil model for the57Co nucleogenic atoms agree perfectly well with the observations of the external irradiation effects in metals; this agreement between internal and external radiation damage concerns the displacement threshold energy and the recoil anisotropy, as well as the recovery mechanism.
