摘要：

We present accurate ab initio numerical solutions of the full Schrodinger equation for the electron-impact ionization of hydrogen near threshold using the propagating exterior complex scaling method. They provide strong support for the Wannier threshold law [Phys. Rev. 90, 817 (1953)], giving sigmaproportional toE(1.122+/-0.015), and also give the energy dependence of the electrons' angular distribution as (pi-theta(12))(FWHM)approximate to3.0E(1/4), in general agreement with classical and semiclassical predictions.
