We have now (4. march 2005) brought the ⁶Li cloud to Fermi degeneracy. The picture shows a cloud of Li atoms trapped in a magnetic field. The picture has been taken in-situ. The Rb cloud is now at approximately 500 nK. The Fermi degeneracy reveals itself via a limit to the size of the cloud: Cooling the Rb cloud further does not reduce the size of the Li cloud.

Description of the apparatus and experimental details are available on our website.
