- Description
- The temperature dependence of Lamb-Mössbauer factor (W) from Mössbauer data has been fitted using numerical calculation in C-language. It is common ground, that the absorption area of the Mössbauer spectrum is proportional to recoilless fraction of Mössbauer atoms (f). In order to study the dynamical lattice properties of the solid is common to use the Debye model. This program allow us to estimate the Debye temperature <math>(\theta_D )\!\,</math>. In spite, the Debye model may be a poor description, particularly for complicated solids or systems with high impurity concentrations, we had perform it in some diluted sample. It is open the possibility to introduce the anharmonicity of the lattice vibrations in order to improve the model.
