- W2363810057 abstract "The radiative correction of self energy of an electron moving with momentum p and emitting absorbing the virtual photon is calculated by the noncovariant quantum perturbation theory to have the form being b 2p 4 . After adding modifications arising from the vacuum polarization and finite nucleus size,we find the Lamb shift (LS) of 2S 1/2 -2P 1/2 states in Hydrogen atom being 1056.522 MHz,smaller than the experimental value 1057.845 MHz by 0.13%. Taking the relativistic modification by Dirac equation into account,the energy differences of 4D 5/2 4 S 1/2 states, the so called Hyper LS and absolute LS of 1 S state in Hydrogen are also calculated with maximum discrepancy up to 6.7%. The reasons are analyzed.For dealing with the divergence,we propose a simple but effective regularization renormalization method,showing that we have to reconfirm the reduced mass first before bringing a finite and fixed modification to it via radiative corrections." @default.
