Abstract: | Effective magnetic moments of drift Rydberg atoms in
strong magnetic fields are obtained for different energy and
angular-momentum states. Classical two-body trajectory
calculations and quantum-mechanical one-body calculations are
employed. For heavy atoms such as rubidium, the trapping dynamics
can largely be explained by the net magnetic moment due to the
cyclotron and the magnetron motion of the Rydberg electron. In
light Rydberg atoms such as hydrogen, the intrinsic two-body
nature of the dynamics becomes manifest in that the ionic motion
significantly contributes to the effective magnetic moment. Also,
light drift Rydberg atoms exhibit an anisotropic response to
field-inhomogeneities parallel and transverse to the
magnetic-field lines. The results are relevant to magnetic
trapping of Rydberg atoms in strong-magnetic-field atom traps. |
