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…
