Paper Abstract

The potential depth of a magneto-optical trap for neutral lithium atoms has been measured to be 0.38 K with a new method in which the escape velocity of laser heated atoms is measured by observing the Doppler shift of the fluorescence. The decay rate constant for the trapped atoms due to ultra-cold collision has been determined to be 1.0 X 10-11 cm3/s, showing no discrepancy with the existing theory based on the fine structure changing collisions.
