Abstract
We consider the dynamics of a neutral atom of magnetic moment mu in a spatially dependent magnetic field. Interaction with a resonant radio- frequency field brings in non-linear dynamics for the slow motion of t he center of mass. We derive asymptotically exact equations for the sl ow dynamics and calculate the frequency of small oscillations for reso nant trapped motions. (C) 1997 Elsevier Science B.V.
