Results are reported of an investigation of the Mossbauer effect on Fe57 nuclei in the paramagnet Al(NO3)3«9H2OFe3+ following simultaneous action of a constant and alternating magnetic field. It is shown that a radiofrequency (RF) field of resonant frequency causes an appreciable broadening of the Mossbauer spectrum components, due to the splitting of the sublevels of the excited state of the Fe57 nucleus.
