Comment on "Sixth-Order Vacuum-Polarization Contribution to the Lamb Shift of Muonic Hydrogen" by T. Kinoshita and M. Nio, Phys. Rev. Lett. 82, 3240 (1999)
Abstract
In the comment we discuss an additional term to the α3 correction to the Lamb shift, which was missed in the calculation by Kinoshita and Nio (Phys. Rev. Lett. 82, 3240 (1999)).
