Sn. Chormaic et al., LONGITUDINAL STERN-GERLACH ATOMIC INTERFEROMETRY USING VELOCITY SELECTED ATOMIC-BEAMS, Journal of physics. B, Atomic molecular and optical physics, 26(7), 1993, pp. 1271-1279
New experiments have been carried out on a velocity selected beam of H
(D) (2s1/2) atoms using a longitudinal Stern-Gerlach atomic interfero
meter. A large number of fringes of the interference pattern has been
observed. The results are in good agreement with theoretical predictio
ns. An application to a topological phaseshift of the Aharonov-Anandan
type is given.
