激光共振电离光谱是一种十分适合于高能量区重元素复杂原子结构研究的技术。为寻找铈原子最佳的共振电离通道 ,利用这一技术对铈原子奇宇称高激发态进行了研究。在 32 0 42～ 34 5 75cm-1范围内 ,用两步共振激发和非共振电离方法 ,首次观察到了 83条铈原子奇宇称高激发态能级 ,测量了这些新能级的能量和给出了可能的总角动量J值
Laser Resonance Ionization Spectroscopy is a technique that is well suited to the study of complex atomic structures of heavy elements in high energy regions. In order to find the best resonant ionization channel of cerium atoms, the odd-parity excited states of cerium atoms were studied by using this technique. In the range of 32 0 42 ~ 34 5 75cm-1, 83 odd-parity high-excited-state energy states of cerium atoms were observed for the first time by two-step resonance excitation and nonresonant ionization methods. The energies of these new energy levels Out of the total angular momentum J value
