摘要：

Two additional positron-atom processes are treated using previously determined [Phys. Rev. 173, 190 1968] variational scattering functions: (1) Positronium formation in e+-H collisions at threshold, and (2) the angular correlation between e+-He annihilation quanta at zero energy. In case (1), we find a large reduction below the Born approximation, in qualitative agreement with other recent theoretical work. In case (2), very close agreement is found with the experiment of Briscoe et al. © 1969 The American Physical Society.
