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 Scattering and Annihilation in H $_{2}$ , N $_{2}$ and CH $_{4}$

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

The recently developed ab initio many-body theory of positron molecule binding [J. Hofierka et al., Nature, 606, 688 (2022)] is combined with the shifted pseudostates method [A. R.…
