Roberts, J. L. and Claussen, N. R. and Cornish, S. L. and Donley, E. A. and Cornell, E. A. and Wieman, C. E. (2001) 'Controlled collapse of a Bose-Einstein condensate.', Physical review letters., 86 (19). pp. 4211-4214.
The point of instability of a Bose-Einstein condensate (BEC) due to attractive interactions was studied. Stable 85Rb BECs were created and then caused to collapse by slowly changing the atom-atom interaction from repulsive to attractive using a Feshbach resonance. At a critical value, an abrupt transition was observed in which atoms were ejected from the condensate. By measuring the onset of this transition as a function of number and attractive interaction strength, we determined the stability condition to be N|a|/aho = 0.459±0.012±0.054, slightly lower than the predicted value of 0.574.
