We have observed Bose-Einstein condensation of sodium atoms. The atoms were trapped in a novel trap that employed both magnetic and optical forces. Evaporative cooling increased the phase-space density by 6 orders of magnitude within seven seconds. Condensates contained up to 5 x 105 atoms at densities exceeding 1014 cm-3. The striking signature of Bose condensation was the sudden appearance of a bimodal velocity distribution below the critical temperature of ~2µK. The distribution consisted of… Expand
Bose-Einstein Condensation of Atomic Hydrogen
The recent creation of a Bose–Einstein condensate of atomic hydrogen has added a new system to this exciting field. The differences between hydrogen and the alkali metal atoms require otherExpand
Bose–Einstein condensation of ultracold atomic gases
Bose–Einstein condensation in a dilute gas of sodium atoms has been observed. The atoms were trapped in an optically plugged magnetic trap or in a cloverleaf magnetic trap. Rf induced evaporativeExpand
Bose-Einstein condensation of lithium
Bose-Einstein condensation of 7Li has been studied in a magnetically trapped gas. Because of the effectively attractive interactions between 7Li atoms, many-body quantum theory predicts that theExpand
Observation of Bose-Einstein Condensation in a Dilute Atomic Vapor
TLDR
A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled and exhibited a nonthermal, anisotropic velocity distribution expected of the minimum-energy quantum state of the magnetic trap in contrast to the isotropic, thermal velocity distribution observed in the broad uncondensed fraction.

Production of a bose einstein condensate of metastable helium atoms
We recently observed a Bose-Einstein condensate in a dilute gas of 4He in the 23S1 metastable state. In this article, we describe the successive experimental steps which led to the Bose-EinsteinExpand
Bose-Einstein Condensation of Molecules
TLDR
It is reported on the Bose-Einstein condensation of more than 105 Li2 molecules in an optical trap starting from a spin mixture of fermionic lithium atoms and demonstrated the magnetic field–dependent mean field by controlled condensate spilling. Expand
