| 摘 要： | 在入射光子能量为79.6 eV～139 eV范围内,利用DS3C模型计算了不同碰撞几何条件下He光双电离的三重微分截面(TDCS),并与3C模型计算结果、CCC理论结果和实验数据做了比较.表明,末态波函数动量相关效应成功地修正了3C结果,特别当入射光子能量接近阈值时,明显改善了与实验结果的符合程度.

| Abstract: | The triple differential cross section for photo-double-ionization of helium are calculated by DS3C model in the range of incident photon energies 79.6?eV～139?eV for various geometries. These calculations are compared with those given by 3C model, the existing CCC results, and the available experimental data. It is shown that the present results, which take the momentum correlation effect of the final-state into account, are in better agreement with experimental data than those of 3C model especially for near-threshold. |
