Recent calculations have shown that multiphoton transitions in a nucleus that involve a γ-ray
photon could be induced by intense fields of optical radiation. The effect of such transitions …

The properties of sidebands in Mössbauer spectra in the presence of a transversal radio-
frequency field have been investigated in iron slabs. The relative intensity of the sidebands …

We consider two possible model time dependences of the local magnetization produced by
the rf field in radio-frequency collapse experiments. For the first model—coherent, periodic …

Experimental and theoretical studies of high-frequency excitations in solids by γ-resonance
spectroscopy are reviewed. Both the resonance-type and non-resonance-type alterations in …

The spectral distribution of the Mössbauer radiation emitted from a radiating nucleus when it
is in the excited vibrational level of a lattice normal mode has been considered theoretically …

The phenomenon of rf sidebands in Mössbauer spectra is used to measure the relaxation
time τ of ultrasonic vibrations in Fe foils. A Co 57 in Fe source, collimator, metallic-Fe …

Résumé Des expériences dans lesquelles des noyaux Mössbauer sont perturbés par les
champs magnétiques de fréquence radio sont passées en revue. De ce point de vue sont …

Within the framework of a unified approach, this paper summarizes a wealth of data on
controlling spectral line shapes in gamma emission of nuclei in solids by stimulating …

Susceptibility measurements, χ′, can be precisely and simply performed in terms of the
relative frequency shift (Δν/ν) of a rf self‐oscillator, occurring when the permeability of the …

We determine the intensity of the nuclear multiphoton sidebands to the forbidden
components of the 14.4-keV Mössbauer transition in Fe 57, generated by the application of …
