内部自由度的最小化是原子冷却到简并温度的一个重要步骤。在这里，我们报道了6 × 10(5)个以最大可能磁量子数m(F) = -4状态的光极化的铥原子加载到工作在532 nm的偶极阱中。用stern - gerlach型实验验证了原子极化的纯度。实验测得的偏振态为m(F) = -3.91 +/- 0.26。
Minimization of internal degrees of freedom is an important step in the cooling of atomic species to degeneracy temperature. Here, we report on the loading of 6 x 10(5) thulium atoms optically polarized at maximum possible magnetic quantum number m(F) = -4 state into dipole trap operating at 532 nm. The purity of polarizations of the atoms was experimentally verified using a Stern-Gerlach-type experiment. Experimental measured polarization of the state is m(F) = -3.91 +/- 0.26.
