Gaussian-basis many-body theory calculations of positron binding to negative ions and atoms

J. Hofierka, B. Cunningham, C. M. Rawlins +2

Positron binding energies in the negative ions H${}^{-}$, F${}^{-}$, Cl${}^{-}$ and Br${}^{-}$, and the closed-shell atoms Be, Mg, Zn and Ca, are calculated via a many-body theory approach develop…
