We present in this study a self-consistent set of scattering cross sections for positron
collisions with water molecules, in the energy range 0.1–10 000 eV, with the prime …

We investigate ionization of atomic hydrogen by electron-and positron-impact. We apply the
Coulomb–Born (CB1) approximation, various modified CB1 approximations, the three body …

The efficiency of tungsten meshes and thin foils for moderation of fast positrons from 22 Na
has been investigated in transmission geometry and a fair agreement has been found with …

Previously, a deep minimum in the measurements of the triply differential cross section
(TDCS) for electron-helium ionization at an incident energy of 64.6 eV was interpreted in …

Ionization collisions by positron impact at low and intermediate energies are investigated by
means of a classical trajectory Monte Carlo (CTMC) simulation. Calculations of fully …

Progress and methods used in positron based studies of inelastic atomic interactions are
traced from the original discovery of the positron to the present. Following a historic overview …

An electrostatic positron beam, incorporating a remoderation stage to yield brightness
enhancement with time-of-flight capabilities, has been developed and characterized. The …

As well as probing matter—antimatter interactions, positrons (as positive electrons) have
been employed to highlight charge and mass effects in the dynamics of collisions, including …

The positron is the antiparticle of the electron, having the same mass but opposite charge.
Positrons undergo collisions with atomic and molecular systems in much the same way as …

We investigate ionization processes induced by positron impact on H 2 by studying the
momentum distributions of the receding ion. To this end, we employ classical trajectory …
