This paper compares the best distorted-wave model results with the most recent experimental data in positron ionization of atomic hydrogen and noble gases. The re-calibration of the experimental measurements yields good agreement with our DCPE5 model

We have carried out calculations for the scattering of positrons from rubidium and cesium in the relativistic close-coupling approximation in the energy range from threshold to 50 eV. The bound states of the atom were represented by frozen-core Dirac

We have used two distorted wave models to calculate positron impact ionization of CH4. 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 mo

We have carried out distorted wave calculations of positron ionization of molecular nitrogen in order to compare with recent experimental measurements. In this work, the nitrogen molecule was represented by a Gaussian wave function. We find that our

For X-ray photon energies in the range E = 0.1 to 25 keV, a calculation of the mean energy to produce an electron-ion pair, w, in gaseous xenon, and the average number of primary electrons produced, N , is carried out, using a detailed Monte Carlo si
