Positronium laser cooling via the - transition with a broadband laser pulse
L. T. Glöggler, N. Gusakova, B. Rienäcker +49
We report on laser cooling of a large fraction of positronium (Ps) in free-flight by strongly saturating the - transition with a broadband, long-pulsed 243 nm alexandri…
A Rydberg hydrogen beam for studies of stimulated deexcitation
Tim Wolz, Maxime Allemand, Daniel Comparat +7
We present a Rydberg hydrogen beamline developed to commission techniques of stimulated deexcitation for application in antihydrogen experiments at CERN's Antiproton Decelerator. T…
Induced THz transitions in Rydberg caesium atoms for application in antihydrogen experiments
Mélissa Vieille-Grosjean, Emiliya Dimova, Zeudi Mazzotta +3
Antihydrogen atoms are produced at CERN in highly excited Rydberg states. However, precision measurements require anti-atoms in ground state. Whereas experiments currently rely on…
Measurement of the Principal Quantum Number Distribution in a Beam of Antihydrogen Atoms
B. Kolbinger, C. Amsler, S. Arguedas Cuendis +35
The ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) collaboration plans to measure the ground-state hyperfine splitting of antihydrogen in a beam at the CERN An…
Stimulated decay and formation of antihydrogen atoms
Tim Wolz, Chloé Malbrunot, Mélissa Vieille-Grosjean +1
Antihydrogen atoms are routinely formed at the Antiproton Decelerator at CERN in a wide range of Rydberg states. To perform precision measurements, experiments rely on ground state…
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…
Efficient positronium production by stimulated decay from the level
M. Antonello, A. Belov, G. Bonomi +48
We investigate experimentally the possibility of enhancing the production of positronium atoms by driving the - and - transitions, overcoming the nat…
