Spectral lines generated by this effect are moved when one nuclear isomer is replaced by another, and in order for this effect to occur E sub R must be less than one-half of the linewidth for the corresponding transition.
Spectral lines generated by this effect are moved when one nuclear isomer is replaced by another, and in order for this effect to occur E sub R must be less than one-half of the linewidth for the corresponding transition. Spectral lines of molecules undergoing this effect display a characteristic namesake "wing". One quantity important in this effect is equal to the exponential of a polynomial involving the absolute value of the scattering vector q, and gives a ratio of transitions via this effect to purely resonant transitions, known as the Debye-Waller factor. Originally discovered in a block of Iridium, this effect was used via a pair of samples of iron attached to loudspeakers in order to prove the existence of gravitational redshift by Pound and Rebka. For 10 points, name this effect in which solid atoms absorb and emit gamma rays in a recoil-free manner, named for a German.
