我们测量了所有自然产生的碱原子第一激发P态(D线)的超精细结构。我们使用高分辨率激光光谱学来解决超精细跃迁，并通过将声光调制器产生的频移锁定到两个跃迁之间的差值来测量间隔。在大多数情况下，由我们的测量得到的超精细耦合常数显著改善了先前的值。
We have measured hyperfine structure in the first-excited P state (D lines) of all the naturally occurring alkali atoms. We use high-resolution laser spectroscopy to resolve hyperfine transitions, and measure intervals by locking the frequency shift produced by an acousto-optic modulator to the difference between two transitions. In most cases, the hyperfine coupling constants derived from our measurements improve previous values significantly.
