阈值附近锂离子的三重光电离
Triple photoionization of Lithium near threshold
摘要：
采用Wigner初始分布数值求解经典四体库仑问题，提出了一种经典-量子混合方法研究Li基态单光子吸收的三重电离.我们确认了Wannier阈值定律$σ\propto E^α$，并且我们表明，在2-5 eV之间的间隔中确定的$α$偏离了我们在$0.1-2$ eV之间的间隔中发现的分析阈值2.16。
英文摘要：
Solving the full classical four-body Coulomb problem numerically using a Wigner initial distribution we formulate a classical-quantum hybrid approach to study triple ionization by single photon absorption from the Li ground state in the threshold region. We confirm the Wannier threshold law $σ\propto E^α$ and we show that the $α$ determined in the interval between 2-5 eV deviates from the analytical threshold value of 2.16 which we find in the interval between $0.1-2$ eV.
