摘要： 用ArF激光(193 nm)光解锑化氢, 首次获得了在波长为403-700 nm间的SbH_2发射光谱, 其辐射寿命为70±20 ns。还检测到了五十余条Sb(6s→5p)在紫外区的光谱谱线以及离子信号。它们都是多光子过程的产物。

Abstract: The 403-700 nm emission spectrum observed in ArF laser photolysis of stibine was recorded for the first time and was assigned to the SbH_2 (Ã~2A_1→X~2B_1) transi- tion. More than fifty emission lines arising from the transitions of Sb (6s→5p) were also observed.
