Premelting as studied by positron annihilation and emission Mössbauer spectroscopies

We have estimated a local heating which takes place owing to the ionization energy losses at the terminal part of a fast positron track and at nano-vicinities of the 57Fe Mossbauer nuclei in case of the emission Mossbauer spectroscopy. It is shown that in experiments close to the melting point one may expect local melting near the probe species.
