2. For our purposes, orbital confinement means that the geometric center of the system is inaccessible to the trapped particle, which must orbit around the excluded middle. Point confinement occurs when the geometric trap center is accessible to the trapped particle.

23. Since the restoring force which would have been supplied by the inner charge bars is provided by the centrifugal potential the inner charge bars may be removed if so desired, just as in the neutron ring case (Ref. 4).

27. Bahns et al. have proposed a complex scheme based on electronic molecular transitions to translationally cool molecules [J. T. Bahns, W. C. Stwalley, and P. L. Gould, J. Chem. Phys. 104, 9689 (1996)]. Another method, based on the stimulated light force due to bichromatic excitation of a two level system [J. Söding, R. Grimm, Yu. B. Ovchinnikov, Ph. Bouyer, and Ch. Salomon, Phys. Rev. Lett. 78, 1420 (1997)], seems to be so efficient at cooling that it might even be useful for moderately open systems such as some molecules (depending on the Franck-Condon factors involved). Yet another option might be to pass the molecular beam through a thin, cold, scattering medium in a fashion analogous to buffer gas loading of traps, although in this case, we would only want to lose about 75% of the translational energy rather than all of it, and we would need to control any diffusive transverse heating (Ref. 6).
