Energy Levels of Mesonic Helium in Quantum Electrodynamics / V.I.Korobov, A.V.Eskin, A.P.Martynenko, F.A.Martynenko // Physical Review A [Electronic resource]. – 2024. – Vol. 109, No. 3. – P. 032802. – URL: https://doi.org/10.1103/PhysRevA.109.032802. – Bibliogr.: 39.

On the basis of the variational method we study the energy levels of pionic helium (π−e−He) and kaonic helium (K−e−He) with an electron in the ground state and a meson in the excited state with principal and orbital quantum numbers n∼l+1∼20. Variational wave functions are taken in the Gaussian form. Matrix elements of the basic Hamiltonian and corrections to vacuum polarization and relativism are calculated analytically in a closed form. We calculate some bound-state energies and transition frequencies which can be studied in the experiment.
