摘要
用WDMI型光栅单色仪直接观测钠原子光谱双线的波长,确定了主量子数n,轨道量子数l,推算出各谱线的归属,并从谱线的裂距经过理论推证,分别计算出精细结构常数α、普朗克常数h和自旋量子数s,这3个重要常数的实测值与公认的理论值比较有较高精度.
The wave length of the twin line of sodium atomic spectra is observed directly with WDMI grating monochromator. Main quantum number n and rail quantum number l are made sure. The ownership of every line is reckoned. The fine structure constant, M. Planck constant and spin quantum number are calculated by the spacing of the twin line. These have high precision compared with theory value.
