Producing long-lived $2{\phantom{\rule{0.16em}{0ex}}}^{3}S$ positronium via $3{\phantom{\rule{0.16em}{0ex}}}^{3}P$ laser excitation in magnetic and electric fields
Producing positronium (Ps) in the metastable 23S state is of interest for various applications in fundamental physics. We report here on an experiment in which Ps atoms are produced in this long-lived state by spontaneous radiative decay of Ps excited to the 33P level manifold. The Ps cloud excitati...
