ECC study in positron impact ionization in molecular hydrogen

The electron capture to the continuum phenomenon in positron impact ionization of molecular hydrogen is studied with the distorted wave Born approximation. Our paper shows that distorted wave Born approximation can produce good triple differential cross-sections when the interaction between the outgoing electron and positron is approximated with the Ward-Macek model. Our theoretical model produces results which are in better agreement with the experiment than the more elaborate models of [J. Fiol, V.D. Rodriguez, R.O. Barrachina, J. Phys. B: At. Mol. Opt.
