GRASIAN: Shaping and characterization of the cold hydrogen and deuterium beams for the forthcoming first demonstration of gravitational quantum states of atoms
Carina Killian, Philipp Blumer, Paolo Crivelli +9
A low energy particle confined by a horizontal reflective surface and gravity settles in gravitationally bound quantum states. These gravitational quantum states (GQS) were so far…
Observation of positronium annihilation in the 2S state: towards a new measurement of the 1S-2S transition frequency
D. A. Cooke, P. Crivelli, J. Alnis +8
We report the first observation of the annihilation of positronium from the 2S state. Positronium (Ps) is excited with a two-photon transition from the 1S to the 2S state where its…
Muonium emission into vacuum from mesoporous thin films at cryogenic temperatures
A. Antognini, P. Crivelli, T. Prokscha +9
We report on Muonium (Mu) emission into vacuum following μ+ implantation in mesoporous thin SiO2 films. We obtain a yield of Mu into vacuum of (38\pm4)% at 250 K temperature and (2…
