Three-color three-step laser resonance ionization spectroscopy has been employed to investigate the autoionization spectra of atomic samarium in the energy region 50,330 - 51,160 cm−1. The measurements were carried out in an atomic beam coupled to a linear time of flight mass spectrometer. Fifty-five odd-parity autoionization levels of atomic samarium in the above-mentioned energy region have been observed using three excitation schemes. Among these, fifty autoionization levels are new. The total angular momenta of eighteen odd-parity autoionization levels have been assigned uniquely.

使用三色共振电离光谱研究原子钐奇数自电离能级

三色三步激光共振电离光谱已被用于研究能量区域 50,330 - 51,160 cm -1中原子钐的自电离光谱。测量是在与线性飞行时间质谱仪耦合的原子束中进行的。已经使用三种激发方案观察到上述能量区域中原子钐的 55 个奇数自电离能级。其中,五十个自电离水平是新的。十八个奇偶性自电离水平的总角动量已被唯一分配。
