Self annihilation of confined positronium
A. R. Swann, D. G. Green, G. F. Gribakin
The effect of confinement on the self-annihilation rate of positronium is studied in three levels of approximation. Artificial restriction of the electron-positron separation leads…
Effect of chlorination on positron binding to hydrocarbons: experiment and theory
A. R. Swann, G. F. Gribakin, J. R. Danielson +3
Measured and calculated positron binding energies are presented for a range of hydrocarbons with up to six carbon atoms (viz., methane, acetylene, ethylene, ethane, propane, butane…
Effect of molecular constitution and conformation on positron binding and annihilation in alkanes
A. R. Swann, G. F. Gribakin
The model-potential approach previously developed by the authors to study positron interactions with molecules is used to calculate the positron binding energy for -alkanes (C$_…
Model-potential calculations of positron binding, scattering, and annihilation for atoms and small molecules, using a Gaussian basis
A. R. Swann, G. F. Gribakin
A model-potential method is employed to calculate binding, elastic scattering, and annihilation of positrons for a number of atoms and small nonpolar molecules, namely, Be, Mg, He,…
Positron Binding and Annihilation in Alkane Molecules
A. R. Swann, G. F. Gribakin
A model-potential approach has been developed to study positron interactions with molecules. Binding energies and annihilation rates are calculated for positron bound states with a…
Calculations of positron binding and annihilation in polyatomic molecules
A. R. Swann, G. F. Gribakin
A model-potential approach to calculating positron-molecule binding energies and annihilation rates is developed. Unlike existing ab initio calculations, which have mostly been app…
