Karshenboim, Savely G.; Ivanov, Vladimir G. und Korobov, Vladimir I. (2018): Low energy levels in neutral muonic helium within a nonrelativistic approach. In: Physical Review A, Vol. 97, No. 2, 22504

Abstract

We consider a nonrelativistic approximation for the neutral muonic helium atom, a three-body system, which consists of an electron, a muon, and a helium nucleus. We discuss the case with the muon in the ground state and study the low energy levels and the transition frequencies of the electron (2s - 1s and 2p - 2s). We treat neutral muonic helium both as a three-body system (with a numerical variational solution) and as a two-body system of an electron bound by a two-body compound nucleus. We compare the results of two approaches and discuss the validity and consistency of fits and of the nonrelativistic approximation.
