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 via inelastic collisions in CF and N gases
A. R. Swann, D. G. Green
Positron cooling via inelastic collisions in CF and N gases is simulated, including positron-positron interactions. Owing to the molecular symmetries, cooling is assumed to…
Many-body theory for positronium scattering and pickoff annihilation in noble-gas atoms
A. R. Swann, D. G. Green, G. F. Gribakin
The many-body-theory approach to positronium-atom interactions developed in [Phys. Rev. Lett. \textbf{120}, 183402 (2018)] is applied to the sequence of noble-gas atoms He-Xe. The…
Many-body theory of positron binding in polyatomic molecules
J. Hofierka, B. Cunningham, C. M. Rawlins +2
Positrons bind to molecules leading to vibrational excitation and spectacularly enhanced annihilation. Whilst positron binding energies have been measured via resonant annihilation…
