The temperature dependence of the intensity of {gamma}-quanta of {sup 109}Ag with an energy of 88 keV, emitted in the horizontal and vertical directions from a single-crystal plate of silver containing {sup 109}Cd, the radioactive decay of which produces excited nuclei of {sup 109}Ag, is investigated. The gamma radiation of this specimen and a control {gamma}-source of {sup 57}CO were recorded by two Ge(Li)-detectors. When the specimen is cooled from 77 K to {approximately} 12 K there is a relative drop in the intensity of {gamma}-quanta of {sup 109}Ag emitted in the horizontal direction by 0.00064 {plus_minus} 0.00044. For the vertical direction the analogous quantity turned out to be of opposite sign and equal to -0.00047 {plus_minus} 0.00051. These preliminary data would appear to favor existing suggestions of a slight broadening of the {gamma}-resonance of the {sup 109}Ag nuclei in silver single crystals. However, in further experiments, in which the accuracy is increased considerably, it will have to be established whether the difference in these quantities is due to some apparatus effects.
