Many-body theory predictions of positron binding energies in five-membered heterocycles involving N, O, S and NH substituents
S. K. Gregg, D. G. Green
Positron binding energies and Dyson orbitals for five-membered heterocycles with N, O, S and NH substituents are predicted \emph{ab initio} via many-body theory. The positron-molec…
Coupled cluster theory for positron binding in anions and polyatomic molecules
Rosario R. Riso, Jan Haakon M. Trabski, Federico Rossi +2
We present the positron coupled cluster singles and doubles (POS-CCSD) method to calculate positron binding energies in molecules. This framework treats electrons and positrons on…
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…
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 [AA] is studied via many-body theory, where includes H, F, Cl and the molecular anions (CN…
