Abstract

We observe Bose-Einstein condensation (BEC) in a dilute atomic gas cooled below 280 nK.87Rb atoms are optically trapped and pre-cooled, loaded into a magnetic trap, and then evaporatively cooled throughthe BEC phase transition. We present results of quantitative studies of condensate fraction, interaction strength, and excitations of the condensate in this system.
