The Oscillations of the Mössbauer Line Shift

Abstract

In the present note the oscillations of the shift of the Mossbauer line in metals connected with the electron-phonon interaction are calculated.The relative shift of the Mossbauer line in a metal considering the interaction * + of conduction electrons with the lattice vibrations is proportional to g ( 6 , k , k )/ /(w (k j) -Q ( 6 , "p -5 ) ) (1). If the renormalized energy of the phonon hG(kj) comes near to the energy change of the electron hQ(G, $ -z), a fast increase of the shift of the Wossbauer line arises. Such resonance increase of the line shift will be observed only for electrons near the Fermi level as they take part in the thermal excitation of the system.
