Producing long-lived 2(3)S positronium via 3(3)P laser excitation in magnetic and electric fields
Original language description
Producing positronium (Ps) in the metastable 2(3)S 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 3(3)P level manifold. The Ps cloud excitation is obtained with a UV laser pulse in an experimental vacuum chamber in presence of guiding magnetic field of 25 mT and an average electric field of 300 V cm(-1). The evidence of the 2(3)S state production is obtained to the 3.6 sigma level of statistical significance using a novel analysis technique of the single-shot positronium annihilation lifetime spectra. The dynamic of the Ps population on the involved levels has been studied with a rate equation model.
