Rudolf Mössbauer has discovered the Mössbauer effect and was honored the Nobel Prize in 1961, based on that the Mössbauer spectroscopy was obtained [ 1 ]. The discovery of the Mössbauer spectroscopy effect is the recoilless (also called: recoil-free) nuclear resonance emission/absorption of γ-rays. In the case of a nuclear transition, the de-excited nucleus is normally recoiled by the momentum of the γ-photon emitted, which makes its resonance absorption impossible by another ground-state nucleus of the same type. However, in solids, recoilless photons can be emitted (and reabsorbed by another ground-state nucleus) with some probability. Mössbauer spectroscopy has utilized in numerous interdisciplinary research applications from core subjects (physics, chemistry, and biology). This spectroscopic technique will be continued to make significant contributions based upon the 2004-2005’s analysis of soil from the Mars surface with spectra collected in-situ [ 2 ].
