Abstract
The use of resonant radiation pressure produced by an axisymmetric light field for collimating atomic beams is considered. As an example the possibility is examined of collimating an atomic beam by the light field created by reflecting a plane wave from the inner surface of a metal cone. It is shown that radiation pressure makes it possible to reduce the transverse velocities of an atomic beam to values of order 100 cm/s, which corresponds to an effective temperature on the order of 0.001 K. A method for obtaining collimated beams of cold atoms that is based on combined slowing-down and collimation of atom beams in response to the pressure of resonant laser radiation is examined. 16 references.
