Background
The phenomenon of nuclear recoil-free emission or resonant absorption of radiation is later referred to as the museum effect. Where the nucleus has a Mossbauer effect, it is referred to as a Mossbauer nucleus. At present, only 100 nuclear transitions of 42 and 80 isotopes of chemical elements (excluding transuranium elements) having the mossbauer effect are found. In particular, no chemical element containing mossbauer species, which is lighter than potassium (K) element, has been found. Most are observed at low temperatures, with only the 1414keV for 57Fe and the 23.87keV nuclear transitions for 119Sn, with greater probability of Mossbauer effect at room temperature. For solids that do not contain mossbauer atoms, a suitable mossbauer nucleus can be artificially introduced into the solid to be investigated, i.e. indirect investigation using the mossbauer nucleus as a probe can also yield a lot of useful information.
