Since the ratio of dand s-wave partial cross sections scales as T 2 in inelastic scattering, the d-wave contribution to photodissociation at 200 mK should be less than 10%, and even smaller for elastic scattering which requires two passages through the centrifugal barrier.

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 evaporative cooling increased the phase-space density by six orders of magnitude. We summarize the different techniques used, and discuss recent studies of properties of Bose condensates with an outlook on future ...

Bose-Einstein Condensation in a Tightly Confining dc Magnetic Trap.

Bose-Einstein condensation of sodium atoms has been observed in a novel “cloverleaf” trap. This trap combines tight confinement with excellent optical access, using only dc electromagnets. Evaporative cooling in this trap produced condensates of 5 3 106 atoms, a tenfold improvement over previous results. We measured the condensate fraction and the repulsive mean-field energy, finding agreement ...

Exergy Analysis of Evaporative Cooling for Optimum Energy Consumption in Diverse Climate Conditions

In this paper, exergy of conditioned air, exergy efficiency, irreversibility, and entropy generation of common models of evaporative cooling have been investigated in five cities of Iran. Direct evaporative cooling (DEC), indirect evaporative cooling (IEC), and two-stage IEC/DEC as the most popular methods of cooling have been modeled. Atmospheric conditions are considered as the dead state of ...

Spin-polarizing cold sodium atoms in a strong magnetic field

The efficiency of evaporative cooling, which is used for the creation of a Bose-Einstein condensate, depends strongly on the number of particles at the start of the evaporation. A high efficiency can be reached by filling the magneto-optical trap with a large number of atoms and subsequently transferring these atoms to the magnetic trap as efficiently as possible. In our case for sodium this ef...
