Abstract

We report the realization of a Bose-Einstein condensate of europium atoms, which is a strongly dipolar species with unique properties, a highly symmetric [Xe]4f76s2S7/28 electronic ground state and a hyperfine structure. By means of evaporative cooling in a crossed optical dipole trap, we produce a condensate of Eu151 containing up to 5×104 atoms. We estimate the scattering length of Eu151 to be as=110(4)aB after comparing the velocities of expansion of condensates to different orientations of the atomic magnetic moments, where aB is the Bohr radius. We observe deformation of the condensate in the vicinity of the Feshbach resonance at 1.32 G with a width of 10 mG.
