Velocity selected production of $2^{3} S$ metastable positronium

C. Amsler, M. Antonello, A. Belov +52

Positronium in the $2^{3} S$ 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 $2^{3} S$ Ps via $3^{3} P$ laser excitation in magnetic and electric fields

S. Aghion, C. Amsler, M. Antonello +62

Producing positronium (Ps) in the metastable $2^{3} S$ state is of interest for various applications in fundamental physics. We report here about an experiment in which Ps atom…

Measurement of antiproton annihilation on Cu, Ag and Au with emulsion films

S. Aghion, C. Amsler, A. Ariga +69

The characteristics of low energy antiproton annihilations on nuclei (e.g. hadronization and product multiplicities) are not well known, and Monte Carlo simulation packages that us…
