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

Hubert J. Jóźwiak, Dimitar Bakalov, Michał Przybytek +2

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