本文报道了以同步辐射为背景光源，在4d亚壳层激发光谱区获得的镉的高分辨光吸收谱。在配备有5000线/mm全息光栅的3 m光谱仪的第一级中记录光谱。长里德堡系列被观察到收敛到两个显着的限制上建立的4d 95 s2母离子配置。这些系列被识别为4d 105 s2 1 S 0至4d 95 s2（2D 52/，2D 32/）np和nf。首次报道了4d 95 s24 f和4d 95 s25 f组态的jK能级结构。新的高分辨率数据揭示了通道间相互作用和自电离效应的例子，这些效应是通过多通道量子亏损理论解释的。
We report new high resolution photoabsorption spectra of cadmium covering the 4d-subshell excitation spectral region using synchrotron radiation as the background source of continuum. The spectra were recorded in the first order of a 3 m spectrograph equipped with a 5000 lines/mm holographic grating. Long Rydberg series are observed converging to two conspicuous limits built on the 4d95s2 parent ion configuration. The series are identified as 4d105s2 1 S0 to 4d95s2(2D52/,2D32/)np and nf. The jK-level structure of the 4d95s24f and 4d95s25f configurations are reported for the first time. The new high resolution data reveal examples of interchannel interactions and autoionization effects which are interpreted by means of the multichannel quantum defect theory.
