RADIATION-INDUCED SIDE-BAND IN A MOSSBAUER SPECTRUM USING SYNCHROTRON-RADIATION

The resonant interactions of SR with nuclei have been studied in the magnetic dipole approximation. The spontaneous emission spectrum of the nuclei interacting with the SR consists of three types of photons with energies E - 2 Delta, E, E + 2 Delta, where E is the energy corresponding to the unperturbed nuclear transition. The relative intensities of the transitions are in the ratios 1:2:1. A conventional ME spectrum, the source being an ensemble of SR excited nuclei and a single-line absorber, will display three resonances; the two outer ones are SR-induced sidebands having equal intensity and width.
