Rydberg-positronium velocity and self-ionization studies in 1T magnetic field and cryogenic environment
M. Antonello, A. Belov, G. Bonomi R. S. Brusa +43
We characterized the pulsed Rydberg-positronium production inside the AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) apparatus in view of antihydrogen formati…
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…
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…
Optical trapping and control of nanoparticles inside evacuated hollow core photonic crystal fibers
David Grass, Julian Fesel, Sebastian G. Hofer +2
We demonstrate an optical conveyor belt for levitated nano-particles over several centimeters inside both air-filled and evacuated hollow-core photonic crystal fibers (HCPCF). Dete…
