Abstract
The problem of observing the Mössbauer resonance absorption of gamma rays from long-lived isomers is briefly outlined, first and foremost for 109mAg taken as an example. Experiments indicative of a small broadening of the Mössbauer gamma line of this isomer in metallic silver are described. This circumstance made it possible to develop and manufacture a gravitational gamma spectrometer and to perform the first experiments with it, which confirm once again the previous data on a small width of the gamma line in question. The broadening factor obtained from these data proved to be 6.3 +5.2−1.9 .
