Abstract

Corrections of order $α^{3} (Z α)^{5} m$ to the Lamb shift and corrections of order $α^{3} (Z α) E_{F}$ to hyperfine splitting generated by the insertions of the three-loop one-particle reducible diagrams with radiative photons in the electron line are calculated. The calculations are performed in the Yennie gauge.
