摘要

应用三库仑波(3C)模型研究了16MeV O7+在散射面上撞击氦的单次电离。给出了不同动量传递的全微分截面(FDCS)。我们的理论结果与最近的实验数据和连续介质畸变波初始状态(CDW-EIS)的结果进行了比较。结果表明，3C计算定性地再现了实验峰结构，特别是在较小的动量传递时。pac: 34.80.Dp

Coulomb three-body effects in the single ionization of helium by 16MeV O^{7+} impact

Three-Coulomb-wave (3C)model is applied to study the single ionization of helium by 16MeV O7+ impact in the scattering plane. Fully differential cross sections (FDCS) is presented for the different momentum transfers. Our theoretical results are compared with the recent experimental data and the results of continuum distortedwave eikonal-initial-state (CDW-EIS). It is shown that the 3C calculations qualitatively reproduce the experimental peak structure, especially at smaller momentum transfers. PACS: 34.80.Dp
