Uehling paper on vacuum polarization refers to the change in the observed charge and the columb potential. I am looking for a formula of the total amount of virtual pairs that surround a charge and not just their net effect. Anyone has an idea where to find such description?

I am trying to find out the density of electron positron pairs around a bare electron charge. In most texts, I saw that the treatment relates to the observed charge vs. the bare charge. I wanted to know if there is a formula that describes the density of electron positron pairs that surround...
