摘要：

We have measured the three-body decay of a Bose-Einstein condensate of rubidium (Rb-87) atoms prepared in the doubly polarized ground state F = m(F) = 2. Our data are taken for a peak atomic density in the condensate varying between 2 x 10(14) cm(-3) at initial time and 7 x 10(13) cm(-3), 16 s later. Taking into account the influence of the uncondensed atoms on the decay of the condensate, we deduce a rate constant for condensed atoms L = 1.8 (+/-0.5) x 10(-29) cm(6) s(-1). For these densities we did not find a significant contribution of two-body processes such as spin dipole relaxation.
