Abstract.

Low energy positron impact ionization of atomic hydrogen is studies theoretically using the hyperspherical partial wave method of Das [1] in constant Q₁₂, equal energy sharing geometry. The TDCS reveal considerable differences in physics compared to electron impact ionization under the same geometry.

Keywords: Hyperspherical; partial wave; collision; ionization; cross section.
