Muon transfer from the excited mesic hydrogen in the metastable 2s-state to helium nuclei

The rate of the molecular charge exchange of the excited muonic hydrogen in the 2s-state on helium nuclei is calculated. Resonance muon transfer is shown to occur with the formation of the intermediate excited complex ((H μ)*He²⁺]2e)*. The resulting rates prove that the muon transfer from the 2s-state alone can not account for the experimental data on the muon transfer frompμ-atoms to⁴He nuclei.
