我们报告了玻色-爱因斯坦凝聚体 (BEC) 的生产成功扩展到稀有原子种类。尽管其自然丰度较低，仅为 0.13%，但 {sup 168}Yb 仍直接蒸发冷却至 BEC。我们的成功演示鼓励人们尝试获得放射性原子的量子气体，从而扩展了量子多体物理和精密测量的可能性。此外，成功形成了{sup 168}Yb BEC和{sup 174}Yb BEC的稳定二元混合物。
We report on the successful extension of production of a Bose-Einstein condensate (BEC) to a rare atomic species. Despite its low natural abundance of 0.13%, {sup 168}Yb is directly evaporatively cooled down to a BEC. Our successful demonstration encourages attempts to obtain quantum gases of radioactive atoms, which extends the possibility of quantum many-body physics and precision measurement. Moreover, a stable binary mixture of {sup 168}Yb BEC and {sup 174}Yb BEC is successfully formed.
