The UCL Positronium Spectroscopy group has recently attended the final EU Marie Curie COHERENCE conference, iCoRD (International Conference on Rydbergs at Durham), where we presented our latest Rydberg Positronium results (PRL. 115, 173001). These results will also be presented at the 29th International Conference on Photonic, Electronic, and Atomic Collisions (ICPEAC) in Toledo, Spain.

We are now attending the 18th International Workshop on Low-Energy Positron and Positronium Physics & the 19th International Symposium on Electron-Molecule Collisions and Swarms (POSMOL) in Lisbon, Portugal, where we will also be presenting our Positronium time-of-flight spectroscopy (NJP. 17, 043059) results, as well as some of our latest results on Positronium at cryogenic temperatures.

The posters giving a brief overview of the contents in each 3 of these sets of results can be found in our Downloads page:
