This paper is a review of low-energy positron interactions with atoms and molecules.
Processes of interest include elastic scattering, electronic and vibrational excitation …

Progress in the ability to accumulate and cool positrons and antiprotons is enabling new
scientific and technological opportunities. The driver for this work is plasma physics research …

The ALPHA collaboration, based at CERN, has recently succeeded in confining cold
antihydrogen atoms in a magnetic minimum neutral atom trap and has performed the first …

The rate of annihilation of low-energy positrons in many molecular gases is orders of
magnitude larger than can be explained on the basis of simple collisions. Developments in …

We present a compilation of recommended positron–molecule cross sections for a range of
scattering processes including elastic scattering, vibrational excitation, discrete electronic …

An intense pulsed positron source has been developed using a buffer gas trap to
accumulate large numbers of positrons and create a dense plasma, which may then be …

Starting from first principles, this tutorial describes the development of the adiabatic-nuclei
convergent close-coupling (CCC) method and its application to electron and (single-centre) …

This paper presents an experimental study designed to address the long-standing question
regarding the origin of very large positron annihilation rates observed for many molecules …

Absolute measurements are presented for the positron-impact cross sections for positronium
formation, direct ionization, and total ionization of the diatomic molecules N 2, CO, and O 2 …

An instrument has been designed and constructed to provide new insights into fundamental,
low energy positron scattering processes. The design is based on the Surko trap system and …
