定向CO2的强场电离理论

Theory of strong-field ionization of aligned CO2

M. Abu-samha, L. B. Madsen

摘要:

提出了一个研究定向分子强场电离的理论框架,并计算了CO2分子的电离产率。我们的计算与最近的实验空前一致。我们发现电离过程受中间共振态的影响,并且依赖于共振态的电离产额并不随初始态的电子密度而变化。该理论解释了半解析理论的失败,如分子隧道理论和强场近似,激发电子结构被忽略。

英文摘要:

A theoretical framework for studying strong-field ionization of aligned molecules is presented, and alignment-dependent ionization yields are computed for CO2. Our calculations are in unprecedented agreement with recent experiments. We find that the ionization process is affected by intermediate resonance states, and the alignment-dependent ionization yields do not follow the electron density of the initial states. The theory explains the breakdown of semi-analytical theories, like the molecular tunneling theory and strong-field approximation, were excited electronic structure is neglected.
