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…

Positron annihilation and binding in aromatic and other ring molecules

E. Arthur-Baidoo, J. R. Danielson, C. M. Surko +6

Annihilation spectra are presented for aromatic and heterocyclic ring molecules resolved as a function of incident positron energy using a trap-based positron beam. Comparisons wit…

Many-body theory calculations of positronic-bonded molecular dianions

J. P. Cassidy, J. Hofierka, B. Cunningham +1

The energetic stability of positron di-anion systems [A $^{-}; e^{+};$ A $^{-}$ ] is studied via many-body theory, where $A^{-}$ includes H $^{-}$ , F $^{-}$ , Cl $^{-}$ and the molecular anions (CN…
