On the afternoon of January 28, 2014, we successfully produced the first molecular BEC of Li2 atoms with our apparatus. The apparatus has a standard design for lithium: Oven, Zeeman slower, MOT, single beam dipole trap. The images show the momentum distribution at a homogeneous magnetic field of 760 G. From right to left, the depth of the dipole trap is reduced, leading to the distinctive bimodal distribution. For small trap depths (far right), a quasi-pure molecular BEC remains.
This is the first molecular BEC in Einstein's birthplace of Ulm, Germany.
