本文报道了光泵锂原子在氦缓冲气体中的扩散系数。在外加磁场和磁场梯度的作用下,光学探测了基态原子的自由感应衰减和自旋回波信号。锂热蒸气在硼硅酸盐玻璃电池中在290和290之间的温度下产生。使用玻璃池的简单设置使锂原子光谱学能够以类似于其他碱金属原子的方式进行,并研究热蒸气相中锂原子的碰撞性质。
We report diffusion coefficients of optically pumped lithium atoms in helium buffer gas. The free-induction decay and the spin-echo signals of ground-state atoms were optically detected in an external magnetic field with the addition of field gradient. Lithium hot vapor was produced in a borosilicate-glass cell at a temperature between 290 and. The simple setup using the glass cells enabled lithium atomic spectroscopy in a similar way to other alkali-metal atoms and study of the collisional properties of lithium atoms in a hot-vapor phase.
