Velocity selected production of metastable positronium
C. Amsler, M. Antonello, A. Belov +52
Positronium in the metastable state exhibits a low electrical polarizability and a long lifetime (1140 ns) making it a promising candidate for interferometry experiments wit…

Producing long-lived Ps via laser excitation in magnetic and electric fields
S. Aghion, C. Amsler, M. Antonello +62
Producing positronium (Ps) in the metastable state is of interest for various applications in fundamental physics. We report here about an experiment in which Ps atom…

Nuclear emulsions for the detection of micrometric-scale fringe patterns: an application to positron interferometry
S. Aghion, A. Ariga, M. Bollani +8
Nuclear emulsions are capable of very high position resolution in the detection of ionizing particles. This feature can be exploited to directly resolve the micrometric-scale fring…
