antiprotonic He/ A3610G Mesonic atoms and molecules, hyperonic atoms and molecules/ He/elRecent measurements of the 2p and 3d atomic levels and lifetimes in antiprotonic helium seem to indicate an inconsistency, when interpreted in terms of an optical potential based on parameters extracted from...

The antiprotonic helium,[equation], is a peculiar metastable atom, interfacing between matter and antimatter. A series of metastable states are composed of the He nucleus, one electron in the ground...Toshimitsu YamazakiYamazaki, T.: In: Karshenboim, S.G., et al. (eds.) The Hydrogen ...
Isotope effects on delayed annihilation time spectra of antiprotonic helium atoms in a low-temperature gas The delayed annihilation time spectra (DATS) of antiprotonic helium atoms have been studied in isotopically pure low-temperature $^{3}\\mathrm{He}$ and $^{... B Ketzer,FJ Hartmann,H ...
While atomcules may resist to million collisions in helium, molecular contaminants such as H2 are likely to destroy them in a single one, down to very low temperatures. In the Born-Oppenheimer framework, we interpret the molecular interaction obtained by ab initio quantum chemical calculations in ...
This review briefly summarises the experimental studies carried out on metastable antiprotonic helium over the last few years, and points out a possible way ahead, assuming that very low-energy antiprotons continue to be available. Very recently, an abundance of new results has been found by ...
Antiprotonic heliumCPT symmetrylaser spectroscopyThe ASACUSA collaboration of CERN has recently carried out two-photon laser spectroscopy of antiprotonic helium atoms. Some nonlinear two-photon transitions of the antiproton at the deep UV wavelengths 位 = 139.8-197.0 were excited by irradiating the ...
