Limiting charge for point nuclei


Journal Article

We investigated the behavior of the vacuum charge around a supercritical nucleus h Z „ÄČ 137 in dependence of the nuclear radius. The screening effects are considered in an effective potential approximation. We show that in the point nucleus limit the nuclear charge is screened by the vacuum charge up to Z = 137. This means that the coupling strength of a point charge in QED cannot be larger than 1. The influence of heavier leptons is also discussed briefly. © 1980, All rights reserved.
