论文摘要
SE的光离谱已通过逐步共振激光电离研究。 Rydberg系列4S $^2 $ 4P $^3 $（$^4 $ s）使用Rydberg系列4S $^2 $ 4P $^3 $（$^4 $ s）文献。 IP和两个相邻的融合限制之间的自动化（AI）光谱获得了$^2 $ 4P $^3 $（$^2 $ D $ _ {3/2} $）和4S $^2 $ 4P $^3 $（$^2 $ d $ d $ _ {5/2} $）。总共观察到，测量和分配了八个AI Rydberg系列。
Photoionization spectra of Se have been studied by step-wise resonance laser ionization. The Rydberg series 4s$^2$4p$^3$($^4$S)np $^3$P$_{0,1,2}$ and 4s$^2$4p$^3$($^4$S)np $^5$P$_{1,2,3}$ were measured via different excitation schemes. Using the Rydberg series 4s$^2$4p$^3$($^4$S)np $^3$P$_2$ with n=15-33, the ionization potential of Se was determined with improved precision to 76658.15(2)$_{stat}$(4)$_{sys}$ cm$^{-1}$, which resolved the discrepancy in previous literatures. Autoionizing (AI) spectra between the IP and two neighboring converging limits of the Se ionic states 4s$^2$4p$^3$($^2$D$_{3/2}$) and 4s$^2$4p$^3$($^2$D$_{5/2}$) were obtained. In total eight AI Rydberg series have been observed, measured and assigned.
