摘　　要：采用包含库仑相关的三体近似末志波函数，计算了入射能为２５０ｅＶ、散射角为３°、５°、７°、９°条件下ｅ－＋Ｈ（２ｓ）→Ｈ＋＋２ｅ－共面反对称三重微分散射截面（ＴＤＣＳ），并与三级修正的ＥＢＳ结果进行了比较。结果发现基态Ｈ电离与亚稳态电离特征有很大的差别。Considering the coulomb correlations in electrons, we calculate the triply differential cross sections for ionization reaction e- +H (2s)→H+ + Ze- in the case of coplanar, asymmetric geometry. Detailed Calculations are performed for incident electron energy of 250eV, scattered angles of 3°, 5°, 7°, 9°, and compared with the EBS results, we find significant departures exist in the ionizations between ground -state and metastable- state H target.
