Within the framework of the recently advanced formulation of QED based on self-energy, we calculate the relativistic rates of the 2{ital S}{sub 1/2}{r arrow}1{ital S}{sub 1/2}+1{gamma} transition in the hydrogen isoelectronic sequence for values of {ital Z} ranging between 1 and 92. We compare our results with those of Johnson (Phys. Rev. Lett. 29, 1123 (1972)) and Parpia and Johnson (Phys. Rev. A 26, 1142 (1982)), analytically and numerically. Although the two approaches are quite different, the formulas for decay rates are shown to be equivalent.
