A series of nonrecoil corrections of order α3(Zα)5m to the Lamb shift, and a series of nonrecoil corrections of order α3(Zα)EF to hyperfine splitting generated by various diagrams were calculated. As such, both the corrections to the Lamb shift and hyperfine could be easily estimated bore the actual calculation was carried out. They were suppressed by an additional factor α/π in comparison with the corrections of the lower order in α.
