Debye Model Calculations of the Mössbauer Effect of 9.3 keV Transition of Kr⁸³ Solid

Abstract

The influence of temperature and pressure on the recoilless fraction and the Mössbauer energy shift for the 9.3 keV transition of Kr^83m is evaluated using the Debye frequency distribution of the lattice vibrations of the Kr solid. The contribution to the recoilless fraction due to the lattice anharmonicity is incorporated and the results are compared with the experiment. “Mössbauer characteristic temperature” Θ_M of 42°K is suggested for the Krypton solid. A strong correlation between the recoilless fraction and the density of the solid is exhibited.
