Density effects in precision laser spectroscopy of exotic helium atoms

Hubert J. JÃ³Åºwiak, Dimitar Bakalov, MichaÅ Przybytek +2

Exotic helium atoms act as unique atomic traps for heavy, negatively charged particles, protecting them from nuclear annihilation and nuclear capture on timescales long enough to e…

Quantum calculation of the collision-induced line-shape effects in antiprotonic helium and the new accurate ab initio $p ˉ$ He $^{+}$ -He potential energy surface

Hubert J. JÃ³Åºwiak, Dimitar Bakalov, MichaÅ Przybytek +2

We present the first fully ab initio calculations of collision-induced broadening and shift of spectral lines in antiprotonic helium ( $p ˉ$ He $^{+}$ ) perturbed by atomic helium.…
