The spectrum of electromagnetic waves emitted by an oscillator trapped in an external
potential well is studied. It is assumed that the natural frequency of the oscillator is much
greater than the frequency of oscillations in the potential well. We consider the quantum
model of emission with regard to the recoil e ect. The highest intensity of the absorption and
emission lines is observed on the natural frequency of the oscillator when the recoil energy is
equal to the energy of the quantum of low-frequency (LF) oscillations in the potential well.
A certain decrease in the amplitude of the emission and absorption lines is noted caused
by the oscillations of the potential well due to, for example, the presence of the phonon
spectrum. The relaxation times of the oscillator LF motion in the potential well, resulted
from the phonon emission, are estimated. It is concluded that these processes have no
in
uence on the observed features of the emission and absorption of high-frequency photons.
This model can be applied to description of the emission and absorption of gamma rays in
the crystal structures even in the presence of the phonon spectrum on condition that the
relaxation time of the LF movements in the potential well is greater than the lifetime of the
HF oscillator.
