| 摘 要： | 利用共振增强多光子电离－－时间飞行质谱技术获得了Ｃｌ原子在２３０－２４５ｎｍ范围内的代振增强多光子电离光谱，共观察到２６条谱线，其中５条是作者新观察到的，这些谱线对应从Ｃｌ原子基态到激发态的双光子跃迁。从中还观察到Ｃｌ原子在强电场中的Ｓｔａｒｋ效应，发现在强场条件下，Ｃｌｄ原子绵基太＾２Ｐ１／２＾０和＾２Ｐ３／２＾０两能级之间的能工位移１．３５ｃｍ＾＝１。而各电子激发态的Ｓｔａｒｋ位移则大致相等，

| Abstract: | The Resonance Enhanced Mutiphoton Ionization(REMPI) spectrum of Cl atom in the range of 230-245nm was obtained. There are twenty six line in the spectrum, anong which five lines are observed for the first time. These lines are due to the transitions from ground state to different excited states by two photon resonance absorption. It is found that the Stark shifts of different excited states are almost same, and they are independent on S, L, J quantum numbers of the excited state. But the difference between two levels 2P 0 1/2 and 2P 0 3/2 of the ground state shifts 1.35cm -1 because of Stark effect. |
