Figure 7. (A) Schematic illustration for emission of specific energy γ-rays from the excited state of nucleus in the Mössbauer source and recoilless γ-rays resonant absorption of the same nucleus in the ground state in the absorber (sample). (B) Nuclear energy levels splitting in case of a transition between Ig = 1/2 and Ie = 3/2 like that of 57Fe due to electric monopole interaction, or electric quadrupole interaction or magnetic hyperfine interaction, and the corresponding 57Fe Mössbauer spectra.
