Abstract

Bose-Einstein condensation of 87Rb has been observed in a vapor cell time-averaged orbiting potential trap, and the trapped condensates have been studied using in situ absorption and dark-ground imaging methods. Condensates of 3 × 104 atoms were observed after 26 s of evaporative cooling. The evaporative cooling sequence consisted of a combination of cooling with ramping magnetic-field strengths and radio-frequency-induced cooling. The measured sizes, numbers of atoms, and transition temperatures of the condensates are consistent with theoretical predictions that include the effects of atomic interactions.
