Abstract
We have produced a sample of free sodium atoms at rest in the laboratory by decelerating atoms in an atomic beam using momentum transfer from a counterpropagating, resonant laser beam. These atoms have a density of about and a velocity spread of about 15 m/s full width at half maximum corresponding to a kinetic temperature less than 100 mK.
