摘要
采用多步激发方式研究了钡原子高激发态光谱特性和组态相互作用，并运用多通道量子亏损理论对实验数据进行了初步分析。通过自电离探测方式可对束缚Ｒｙｄｂｅｒｇ系列和自电离Ｒｙｄｂｅｒｇ系列同时进行研究。
Multistep-excitation scheme has been used to investigate spectroscopic characteristics of highly-excited states of atomic barium, as well as the configuration interaction between channels. Multichannel quantum defect theory has been employed to analyze the experimental data. The detection scheme with autoionization has been demonstrated in measuring both bound and autoionizing Rydberg states in the same experimental setup, and shows various advantages.
