Abstract
For the excitation of high-intensity ultrasonic waves a second harmonic is generated in a Moessbauer absorber, where in combination with the satellites omega //0 plus or minus n OMEGA (n equals 1, 2, 3,. . . . ) of the unshifted line it produces new ″natural″ lines at frequencies omega //0 plus or minus n2 OMEGA (n equals 1, 2, 3,. . . ) and alters considerably the entire absorption spectrum. The amplitudes of the fundamental and secondary modes are determined from the spectra obtained for a sodium nitroprusside powder sample, making it possible to estimate the anharmonicity coefficients.
