Mössbauer effect
/ˈməːsbaʊə
/noun Chemistry
An effect in which certain atomic nuclei bound in a crystal emit gamma rays of sharply defined frequency which can be used as a probe of energy levels in other nuclei.Using the Mössbauer effect to measure the velocity of the basilar membrane, he made a significant discovery....
- Isolated nuclei will not exhibit the Mössbauer effect because their motions cause Doppler shifts in the energies of the ray and the peak resonant energy producing a mismatch in these energies.
- The Mössbauer effect is a recoilless absorption and emission of a photon.
Origin
1960s: named after Rudolf L. Mössbauer (born 1929), German physicist.
