A Proposal for Optically Cooling Atoms to Temperature of 10−6 Kssible to cool sodium atoms to temperatures of 10.K or less. These low temperatures correspond to velocities less than the recoil velocity of an atom emitting a single resonant photon. Although the method is straightforward in principle, it anticipates the demonstration of optical traps capable of l

These results are preliminary,and we expect that further work will provide substantial improvements in our final temperature and density. This is an extremely simple and in

Either atom can actually be excited and subsequently reemit the resonance photon ħω.

Laser-Induced Nuclear Orientation of 1 ,s ,Rbular anisotropy of the nuclear gamma ray emission. The profiles of anisotropy versus laser tuning yield atomic resonance frequencies from which nuclear moments and other structure parameters are derived. Prior to the present study, a number of experiments were performed using lamps as light sources,
