Radiative corrections to atomic photoeffect and tip bremsstrahlung. III

The radiative corrections to the photoeffect from the Kshell were evaluated recently by McEnnan and Gavrila assuming a hydrogenlike atomic model. The result was expressed in the form of a corrective factor [1+(\frac{\ensuremath{\alpha}}{\ensuremath{\pi}})\ensuremath{\delta} multiplying the basic photoeffect differential cross section. An expression for \ensuremath{\delta} correct to lowest order in \ensuremath{\alpha}and...
