| 摘 要： | 电子关联效应在负离子中的作用相当重要，本文讨论了负碳离子（２ｓ＾２２ｐ＾２）和（２ｓ＾１２ｐ＾４）的能级结构、光谱跃迁、寿命和光离解通道等。碳负离子（１ｓ＾２２ｓ＾１ｐ＾４）的双重态比四重态稳定，（２ｓ＾２２ｐ＾４）和（２ｓ＾１２ｐ＾４）之间各辐射谱线波长位于超紫外区域的上限附近，其光谱强度很大的波长有６条，为研制Ｘ射线激光提供了有利的工作物质。

Photodetachment of the Negative Cabon Ion (2s22p3) and (2s12p4) |
| |
| Abstract: | Electron electron correlation is more significant in negative ions than neutral atoms, often dominating the atomic structure of the ion and the cross section for interaction with an extrenal field. The negative carbon ion (2s 22p 3) and (2s 12p 4) levels, wavelength, radiative lifetime and photodetachment are discussed. The double states (1s 22s 12p 4) of negative carbon ion are more steady than its quartet states. The wavelength between (2s 22p 3) and (2s 12p 4) is located near XUV and 6 strong wavelengths are given. It can offer material for X ray laser. |
