Dissociative positronium attachment in halogen gases
R. S. Wilde, G. F. Gribakin, I. I. Fabrikant
We suggest that the observed large annihilation rates of ortho-positronium (-Ps) in halogen gases are due to the process of dissociative Ps attachment, ${\rm Ps} + X_2 \to {\rm…
Generation of photoionized plasmas in the laboratory of relevance to accretion-powered x-ray sources using keV line radiation
D. Riley, R. L. Singh, S White +12
We describe laboratory experiments to generate X-ray photoionized plasmas of relevance to accretion-powered X-ray sources such as neutron star binaries and quasars, with significan…
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…
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…
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…
