Phys. Rev. Lett. 78, 3801–3805 (1997)Emergence of Interaction Effects in Bose-Einstein CondensationReceived 7 November 1996; published in the issue dated 19 May 1997 We present a quantitative evaluation of the predictions of mean-field theory for describing a Bose-Einstein condensate in a magnetic trap by comparing directly with experimental observations. We study the release energy from ballistic expansion and the cloud density profile as a function of mean-field effects. Significant departure of the cloud shape from both the noninteracting limit and the strongly repulsive limit is observed for our parameters, consistent with theoretical prediction. © 1997 The American Physical Society URL:
