Measured Properties of an Antihydrogen Beam / Hunter, E. D. ; Bumbar, M. ; Amsler, C. ; Bayo, M. N. ; Breuker, H. ; Cerwenka, M. ; Costantini, G. ; Ferragut, R. ; Giammarchi, M. ; Gligorova, A. et al. /Asacusa AD-3
We report a factor of 100 increase in the antihydrogen beam intensity downstream of ASACUSA’s Cusp trap: 320 atoms detected per 15-minute run. The beam contains many Rydberg atoms, which we selectively ionize to determine their velocity and binding energy. [...]

Laser spectroscopy of long-lived antiprotonic and pionic helium in superfluid helium / Hori, M (Mainz U. ; Munich, Max Planck Inst. Quantenopt.) ; Aghai-Khozani, H (Mainz U.) ; Sótér, A (Mainz U.) ; Dax, A (PSI, Villigen) ; Barna, D (CERN) ; Venturelli𝑒, L (INFN, Pavia ; Brescia U.)
The PiHe collaboration of PSI recently carried out laser spectroscopy of an infrared transition in three-body pionic helium atoms that were synthesized in a superfluid (He-II) helium target. Analogous measurements of antiprotonic helium atoms embedded in liquid helium were carried out by the ASACUSA collaboration of CERN. [...]
