摘要

采用双色三步激发和光电离过程,对Sm原子的偶宇称高激发态的光谱进行了研究.先采用两条激发路线分别将Sm原子两步共振激发至待测的高激发态,然后利用光电离技术对其进行探测.分别将第一束激光的波长固定在627.50nm和624.41nm上,以便将Sm原子从亚稳态共振激发到由4f66s6p电子组态所构成的两个原子状态上.第二束激光在440700nm的波段范围内扫描,不仅使Sm原子在3004038065cm-1能域内的偶宇称高激发态上布居,将其进一步光电离,测量了其光谱.通过光谱定标和选择定则等分析手段,本工作不仅精确获得了136个态的能级位置,而且也唯一确定了其总角动量,并且给出了相关跃迁的相对谱线强度.

Abstract

Spectra of even-parity highly excited states of the Sm atom have been systematically studied with two color three-step excitation and photoionization detection method. With two different excitation paths, the atom is resonantly excited to given bound states where it is detected by photoionization. The wavelength of the first laser is fixed at 627.50 nm or 624.41 nm so that the Sm atom can be excited to the two different intermediate states with the 4f66s6p configuration. Then the wavelength of the second laser is scanned from 440-700 nm to further excite the atom, so that the highly excited states in the 30040-38065 cm-1energy region can be populated. Based on precise calibration of wavelength and the selection rules, the level energies of 136 even-parity states and their relative line intensities are determined with a unique assignment of the J momentum. Except for the level energies of 71 even-parity states are confirmed by the present work, all information mention above has not been reported previously.
