摘要
对铀原子单色和双色多光子共振电离光谱开展了深入的研究。报道了用双色三步共振光电离技术测量位于 330 0 3～ 34 2 6 4cm- 1 范围内的奇宇称高激发态能级的位置。利用总角动量选择定则指定了这些能级的总角动量 J值。
Single-colour and two-colour multiphoton res on ant ionization spectra of uranium atom were studied extensively with a Nd:YAG la ser-pumped dye laser atomic beam apparatus time-of-flight mass spectrometer i n our laboratory.The energy locations of high-lying odd-parity levels in the r egion 33 003—34 264 cm- -1,mearured by a two-colour three-step ionizati on technique,were reported here.The angular momentum quantum number J was un iquely assigned for these levels by using angular momentum selection rules.
