B-Spline basis Hartree-Fock method for arbitrary central potentials: atoms, clusters and electron gas
D. T. Waide, D. G. Green, G. F. Gribakin
An implementation of the Hartree-Fock (HF) method capable of robust convergence for well-behaved arbitrary central potentials is presented. The Hartree-Fock equations are converted…
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…
Positron cooling and annihilation in noble gases
D. G. Green
Understanding the dynamics of positron cooling in gases, including the fraction of positrons surviving to thermalisation, is critical for accurate interpretation of positron lifeti…
Probing positron cooling in noble gases via annihilation spectra
D. G. Green
spectra for positron annihilation in noble-gas atoms are calculated using many-body theory for positron momenta up to the positronium-formation threshold. This data is used, to…
Enhancement factors for positron annihilation on valence and core orbitals of noble-gas atoms
D. G. Green, G. F. Gribakin
Annihilation momentum densities and correlation enhancement factors for low-energy positron annihilation on valence and core electrons of noble-gas atoms are calculated using many-…
Comment on "Gamma-ray spectra from low-energy positron annihilation processes in molecules"
D. G. Green, G. F. Gribakin
In the article by Ma~\emph{et al.}~[Phys.~Rev.~A {\bf 94}, 052709 (2016)], -ray spectra for positron annihilation on molecules were calculated in the independent-particle approx…
