摘要: A derivation is given of the exact form three-body Coulomb wavefunction in asymptotic region where separation all particles tends to infinity. Using a modification method Pluvinage (1951), an approximate scattering derived that satisfies this boundary condition. Triply-differential cross sections (TDCS) for electron impact ionisation atomic hydrogen calculated with wavefunction, which contains no free parameters, show excellent agreement measurements at energies greater than 150 eV. The corresponding TDCS positron are also presented.
