Abstract

It is demonstrated that when in a standard Mössbauer spectroscopy experiment two different hyperfine magnetic field distributions describe experimental data equally well, measurements by means of a monochromatic circularly polarized source lead to the correct choice of the solution. The problem of the asymmetry of the spectrum in the case of a polarized source and pure magnetic interaction is discussed and constraints for the line intensities are given.
