Accurate measurements are presented of the rate of trap-loss-producing collisions between ultracold magneto-optically trapped Li atoms for a range of trap laser intensities and frequencies. Intensities from near the atomic saturation intensity to well above it are investigated. At low intensities, fine-structure-changing collisions cause trap loss with a rate constant of -10 ' cm /s. At sufficiently high intensity, the trap can be deep enough to effectively freeze out the dominantdoi:10.1103/physreva.51.r890 pmid:9911776 fatcat:argq2hz6avfo5lvau7w3opk77e
