Positronium energy levels at order mα7: Vacuum polarization corrections in the two-photon-annihilation channel

TL;DR: In this article, all contributions to the energy levels of parapositronium at order m α 7 coming from vacuum polarization corrections to processes involving virtual annihilation to two photons were calculated.
Journal ArticleDOI

Laser spectroscopy of muonic atoms

TL;DR: In this paper, a source of very slow positive muons is developed which employs laser photoionization of muonium, which is used for testing the Quantum Electrodynamics of bound states, for precise measurements of fundamental constants, for investigating properties of hadronic nuclei, and for searching for anomalous muon interactions.
Journal ArticleDOI

Chemistry and physics with many positrons

TL;DR: The first study of a high-density collection of positronium (Cassidy et al., 2005) revealed Ps-Ps spin exchange interactions in a porous silica sample as discussed by the authors.

Positronium energy levels at order $m \alpha^7$: vacuum polarization corrections in the two-photon-annihilation channel

TL;DR: In this article, the authors calculated all contributions to the energy levels of parapositronium at order $m \alpha^7$ coming from vacuum polarization corrections to processes involving virtual annihilation to two photons.
