✦ Synopsis

We have used two distorted wave models to calculate positron impact ionization of CH 4 . In the first one we used Gaussian molecular target representations and in the second we assumed that the target is a sum of independent atoms. We found that our molecular model works better than the ''independent atoms'' model.

The hyperspherical hidden crossing method (HHCM) is used to investigate positron impact ionization of hydrogen near threshold. An important feature of this method is that it can provide valuable insight into scattering processes. In the calculation of positron-hydrogen ionization, the adiabatic Hami

A 3C approximation which was employed in the study of the ECC phenomenon in positron impact ionization of H 2 is now applied to positron impact ionization of helium. Our absolute triple differential cross sections are used to calibrate the existing experimental data.
