的和光谱已经研究了从各自的阈值到各自的三重电离势的阈值光电子符合（TPEsCO）光谱。和（在Ne和Ar，分别为n = 2，3）的状态，以及卫星状态，其中两个电子被弹出，一个被提升到一个未填充的轨道，已被观察到。这项研究是第一次广泛的观察卫星状态的dications的电子发射光谱，并扩展了以前的观察光学发射光谱的三重电离阈值的区域。新的功能已被识别的光谱和分配的基础上提出以前的结果从光学光谱和计算与原子多组态狄拉克-福克代码。
The and spectra have been studied from their respective thresholds up to their respective triple ionization potentials by threshold photoelectrons coincidence (TPEsCO) spectroscopy. The and (n = 2, 3 in Ne and Ar, respectively) states of the dications as well as the satellite states, where two electrons are ejected and one is promoted into an unfilled orbital, have been observed. This study is the first extensive observation of the satellite states of dications by electron emission spectroscopy and extends the previous observations by optical emission spectroscopy to the region of the triple ionization threshold. New features have been discerned in the spectra and an assignment is proposed based on previous results from optical spectroscopy and on calculations with an atomic multiconfigurational Dirac - Fock code.
