准分子离子Kr+Li的真空紫外发射及其电子束激发动力学
Vacuum-ultraviolet Emission of Ionic Excimer Kr+Li and Excitation Dynamics by Relativistic e-beam Pumping
摘要
由相对论电子束激发稀有气体Kr和碱金属Li的混合蒸气,观察到来自Kr+Li准分子离子的真空紫外发射带(147 nm和149 nm)。讨论了发射光谱的温度和气体密度依赖特性以及电子束激发的动力学过程。经理论计算,两个发射带被分别标识为(KrLi)+离子准分子的21Σ+→11Σ+和11Π→11Σ+跃迁。另外,在Xe/Li混合蒸气中观察到的186 nm和189 nm辐射带也被标识为准分子离子Xe+Li对应能级之间的跃迁。
Abstract
A gas mixture of krypton with a hot vapor of lithium was excited to obtain two diffuse vacuum-ultraviolet emission bands centered at 147 and 149 nm. The observed emission bands are assigned to the 21Σ+→11Σ+ and 11Π→11Σ+ transitions of (KrLi)+ ionic excimer. A similar band with two peaks at 186 and 189 nm from electron-beam-pumped Xe/Li mixtures was believed to be the same transitions of (XeLi)+ excimer.
