摘要:

本文报道了用磁场扫过种间s波费什巴赫共振,首次产生了两种费米子种6Li和40 K的超冷玻色子异质结分子。这使我们能够以高达50%的高效率关联高达4x10^4个分子。使用直接成像的分子,我们测量增加的寿命的分子接近共振超过100毫秒的分子-原子混合物存储在谐波陷阱。

英文摘要:

We report on the first creation of ultracold bosonic heteronuclear molecules of two fermionic species, 6Li and 40K, by a magnetic field sweep across an interspecies s-wave Feshbach resonance. This allows us to associate up to 4x10^4 molecules with high efficiencies of up to 50%. Using direct imaging of the molecules, we measure increased lifetimes of the molecules close to resonance of more than 100 ms in the molecule-atom mixture stored in a harmonic trap.
