positrons with molecules with emphasis on resonances, positron attachment, and …

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

Publisher Summary This chapter discusses resonance and threshold phenomena in low-
energy electron collisions with molecules and clusters. Low-energy collisions of electrons …

Recent research has shown that there are a number of atoms and atomic ions that can bind
a positron. The number of atoms known to be capable of binding a positron has expanded …

Scattering phase shifts and annihilation rates for low-energy positrons interacting with noble
gas atoms are calculated ab initio using many-body theory implemented in the Gaussian …

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 …

Positron scattering and annihilation on noble-gas atoms is studied ab initio using many-
body theory methods for positron energies below the positronium formation threshold. We …

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 …

A two-parameter semiempirical theory of positron scattering and annihilation is developed
and used to investigate the behavior of positrons interacting with the rare gases and metal …

Enhanced positron annihilation on polyatomic molecules is a long-standing and complex
problem. We report the results of calculations of resonant positron annihilation on methyl …
