Pick-off annihilation of positronium in matter using full correlation single particle potentials: solid He
A. Zubiaga, F. Tuomisto, M. Puska
We investigate the modeling of positronium (Ps) states and their pick-off annihilation trapped at open volumes pockets in condensed molecular matter. Our starting point is the inte…

Matter-positronium interaction: An exact diagonalization study of the He atom - positronium system
A. Zubiaga, F. Tuomisto, M. J. Puska
The many-body system comprising a He nucleus, three electrons, and a positron has been studied using the exact diagonalization technique. The purpose has been to clarify to which e…
