摘要：

Recent work on nonperturbative (in Zalpha) calculations of quantum electrodynamic (QED) effects in high-Z few-electron atoms is reviewed. Topics covered are precise calculations of the Coulomb self energy in hydrogenic atoms, nuclear size effects on the self energy, and electron screening effects on the self energy and vacuum polarization. Various computational methods are compared.
