Description

We have investigated the properties of Bose-Einstein condensates of sodium atoms in the upper hyperfine ground state. Condensates in the high-field seeking |F=2,mF=-2> state were created in a large volume optical trap from initially prepared |F=1,mF=-1> condensates using a microwave transition at 1.77 GHz. We found condensates in the stretched state |F=2,mF=-2> to be stable for several seconds at densities in the range of 1014 atoms/cm3. In addition, we studied the clock transition |F=1,mF=0>→|F=2,mF=0> in a sodium Bose-Einstein condensate and determined a density-dependent frequency shift of (2.44±0.25±0.5)x10-12 Hz cm3
