Spatial confinement of muonium atoms
K. S. Khaw, A. Antognini, T. Prokscha +4
We report the achievement of spatial confinement of muonium atoms (the bound state of a positive muon and an electron). Muonium emitted into vacuum from mesoporous silica reflects…

Testing antimatter gravity with muonium
Klaus Kirch, Kim Siang Khaw
The debate about how antimatter or different antimatter systems behave gravitationally will be ultimately decided by experiments measuring directly the acceleration of various anti…

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…
