Relaxation effects in mössbauer transmission and scattering. II Introduction of relaxation

F. Hartmann-Boutron

In part I of this paper (ref. [1]) we have studied Mössbauer transmission and scattering in the absence of relaxation. Here we introduce relaxation. We find that the refraction index observed in a transmission experiment only depends on one Liouville matrix, while the scattered spectrum involves a sum of three products of three Liouville matrices. It follows that scattering is not a very good method to study relaxation except for the case of population relaxation at finite temperature. On the contrary comparison between emission and transmission spectra might give useful information on electronic rearrangement effects in source experiments.
