Abstract
Two observations of nuclear forward scattering of Mössbauer radiation are presented. In one, a magnetic-resonance device was used to chop the γ-ray beam. After the beam was turned off, the nuclear target became a strong emitter of γ-rays in the forward direction. In the other observation, the energy of the intermediate excited nuclear state was changed suddenly by a hyperfine magnetic field reversal and the de-excitation of the nuclei occurred with the forward emission of γ-rays at the shifted frequency. In both cases, the enhancement of the radiative channel of nuclear scattering was observed.
