摘　　要：利用Poincaré截面和标度回归谱理论对平行电磁场中高里德堡态锂原子自电离现象进行了半经典分析.并与相同条件下氢原子的相应性质进行比较,结果表明两者有很大不同,这主要是由于离子实散射引起的.从而表明离子实对非氢原子的混沌性质起着非常重要的作用.Using Poincare surface of section method and scaled recurrence spectra approach,we semiclas-sically analyze the autoionization of Rydberg lithium atoms in parallel electric and magnetic fields.The results are compared with those of hydrogen atoms under the identical conditions,which indicate that the substantial discrepancies between the both mostly arise from the contributions of core scattering.Our work therefore confirms the considerable role of core scattering in inducing chaos for multielectron at-oms.
