Fiftyfold Improvement in the Number of Quantum Degenerate Fermionic Atoms
Fiftyfold Improvement in the Number of Quantum Degenerate Fermionic Atoms
We have produced a quantum degenerate 6Li Fermi gas with up to 7 x 10(7) atoms, an improvement by a factor of 50 over all previous experiments with degenerate Fermi gases. This was achieved by sympathetic cooling with bosonic 23Na in the F=2, upper hyperfine ground state. We have also …
