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…
Calculations of positronium-atom scattering using a spherical cavity
A. R. Swann, G. F. Gribakin
Positronium (Ps) scattering by noble-gas atoms (He, Ne, Ar, Kr, and Xe) is studied in the frozen-target approximation and with inclusion of the van der Waals interaction. Single-pa…
Vibrational Feshbach Resonances Mediated by Nondipole Positron-Molecule Interactions
M. R. Natisin, J. R. Danielson, G. F. Gribakin +2
Measurements of energy-resolved positron-molecule annihilation show the existence of positron binding and vibrational Feshbach resonances. The existing theory describes this phenom…
