Spontaneous emission of a confined atom

Abstract
Modifications of a natural emission line of a free atom, due to its concentrated center of mass wave-function, have been studied. The Doppler shifts, associated with the corresponding momenta distribution of the wave packet, are responsible for the shape of the emitted line. We found, that the modifications of the emission line shape do not cause any changes in the life time and the total radiation intensity.
