The cerium spectrum emitted by an electrodeless lamp has been observed with a SISAM spectrometer in the region from 0.82 to 2.42 m. Of the 2076 lines observed, about 1100 lines have been classified as transitions in the energy level system of Ce I and 400 lines in Ce II. The average deviation between the observed wave numbers and those calculated from the two energy levels is ±0.023 cm
利用SISAM光谱仪在0.82至2.42米的区域内观测了无极灯发射的铈光谱。在所观测的2076条谱线中,约1100条谱线已被归类为Ce I能级系统中的跃迁,400条谱线归类为Ce II中的跃迁。观测波数与由两个能级计算出的波数之间的平均偏差为±0.023厘米。
