Atomic beam deflection by resonant light pressure

A method is proposed for generating a near-monoenergetic atomic beam by deflection resulting from the pressure of light of a resonance frequency. A system in which a beam of atoms passes through N periodically distributed regions of interaction with laser radiation is considered: the system ensures a high selectivity in respect of the atomic velocities. The following applications of deflection of monoenergetic atoms are considered: analysis of the velocity distribution in an atomic beam, determination of the lifetime of excited atomic states, and testing of the theory of photon statistics.
