Many-body theory and Gaussian-basis implementation of positron annihilation $γ$ -ray spectra on polyatomic molecules

S. K. Gregg, J. P. Cassidy, A. R. Swann +3

Doppler-broadened $γ$ -ray spectra for positron annihilation on molecules are calculated using many-body theory. By employing Gaussian bases for the electron and positron wavefuncti…

Many-body theory calculations of positron binding to parabenzoquinone

S. K. Gregg, J. Hofierka, B. Cunningham +1

Positron binding in parabenzoquinone is studied using \textit{ab initio} many-body theory. The effects of electron-positron correlations including polarization, virtual positronium…
