Abstract
Bose-Einstein condensation of sodium atoms has been observed in a nove l ''cloverleaf'' trap. This trap combines tight confinement with excel lent optical access, using only de electromagnets. Evaporative cooling in this trap produced condensates of 5 x 10(6) atoms, a tenfold impro vement over previous results. We measured the condensate fraction and the repulsive mean-field energy, finding agreement with theoretical pr edictions.
