Scattering in $e^{-}-(p{e}^{-})$ and ${\mu }^{-}-(p{\mu }^{-})$ systems: mass dependent and mass independent features of cross sections above the degenerated thresholds

V. A. Gradusov, S. L. Yakovlev

Ab initio calculation of low energy scattering of electrons (muons) off hydrogen (muonic hydrogen) are performed on the basis of Faddeev-Merkuriev (FM) equations. The explicit cont…
