内容記述 |
The sub-nanometer amplitudes of the samples vibrated with high frequencies were measured by 57Fe Mossbauer spectroscopy using a nuclear Bragg monochromator and focusing optics. The Mossbauer spectra of the vibrated single-line absorber showed comb-like absorption peaks due to the frequency modulation of the gamma rays, and the amplitudes of the absorbers were determined by the sideband intensities. We used the stainless-steel foil glued on the quartz crystal or the polyvinylidene fluoride (PVDF) film as samples. The mean value and the variance of the amplitude in sub-nanometer order were obtained for the irradiated area of 100 μm diameter in the sample. We could obtain the sub-nanometer amplitude with almost zero variance, using the 57Fe synchrotron Mossbauer source and focusing optics for the PVDF film. Therefore, this method makes it possible to produce the high-quality coherent frequency-modulated gamma rays. This method is useful for the control of gamma rays. This work will advance X-ray quantum optics and quantum technology applications using a single gamma photon. |
