利用高分辨原子束激光光谱学研究了K原子的斯塔克效应。一种紧凑的电极装置已被开发，以产生稳定和强大的电场。测量了D1和D2线的斯塔克位移以及D2线的分裂，发现它们与电场的平方成正比。确定了D1线的标量极化率和D2线的标量和张量极化率为α s（4 p 2 P 1/2）-α s（4 s 2 S 1/2）=81.3±2.4 kHz/（kV/cm）2，α s（4p 2 P3/2）-α s（4s 2S 1/2）=93.0± 2.5kHz/（kV/cm）2，α t（4p 2 P3/2）=-27.6 ~0.7kHz/（kV/cm）2，与先前报道的值进行了交叉检验。
High-resolution atomic-beam laser spectroscopy has been performed to study the Stark effect of K atoms. A compact electrode apparatus has been developed to produce a stable and strong electric field. The Stark shifts of the D 1 and D 2 lines as well as the splitting of the D 2 line have been measured and found to be proportional to the square of the electric field. The scalar polarizability of the D 1 line and the scalar and tensor polarizabilities of the D 2 line have been determined to be α s (4 p 2 P 1/2 ) -α s (4 s 2 S 1/2 )=81.3±2.4 kHz/(kV/cm) 2 , α s (4 p 2 P 3/2 ) -α s (4 s 2 S 1/2 )=93.0±2.5 kHz/(kV/cm) 2 , and α t (4 p 2 P 3/2 )=-27.6±0.7 kHz/(kV/cm) 2 , respectively, providing a crosscheck of the previously reported values.
