我们应用耦合通道光学方法，正电子-氢原子散射的电离阈值以上的能量为40 eV。重排正电子偶素通道采用包含原子靶态的密耦合方法处理。通过从头算光学势模型，考虑到忽略的连续。物理观测，如电离，电子偶素形成，总截面与弹性和电子偶素（1 s）微分截面一起提出。
We apply the coupled-channel-optical method for positron-hydrogen atom scattering at energies just above the ionization threshold to 40 eV. The rearrangement positronium channels are treated in the close-coupling method that includes the atomic target states. The neglect of the continuum is taken into account via an ab initio optical potential model. Physical observables such as ionization, positronium formation, and total cross sections are presented together with elastic and positronium( 1s) differential cross sections.
