A major effect was found that had defied the construction of a completely satisfactory explanation in terms involving only conventional processes of incoherent excitation. It was the generation of radiofrequency sidebands on the hyperfine Moessbauer spectra of /sup 57/Fe in ferromagnetic environments. Through the application to a ferromagnetic iron foil of a magnetic field oscillating at radiofrequencies, several new spectral lines were produced in addition to the usual six hyperfine components of the 14.4-keV transition in /sup 57/Fe. A persistent complication arose from the geometry in which the radiofrequency H field was generally applied in the plane of the absorber foil, so that magnetostriction occurred in the direction perpendicular to the axis of propagation of the gamma radiation. Very significant was the result that unlike the paramagnetic case this new model predicted a dependence of sideband intensity upon power that was drastically different from the magnetostrictive theories. Even more significant was that the new multiphoton model of nuclear sidebands was comprehensive enough to suggest new extrapolations and effects not previously apparent. The most exciting was the extensive range over which sidebands might be tuned.
