Vacuum Polarization and the Electric Charge of the Positron
... Because the net vacuum polarization charge is quadratic in the nuclear charge Z, it is impossible to simultaneously adjust the electron-positron and electron-proton charge differences such that all atoms are neutral, without satisfying the bound (10). Since the momentum integrations in (8) involve o ...

Gamow`s Theory of Alpha Decay
... There has been the fact that previous findings which relate lambda (or half-life) with the energy and Z, could be obtained using this last term, which is nothing more than an approach of the Gamow’s theory of Geigger-Nuttal equation. Using last approximation, we can obtain the Gamow’s factor for U-2 ...
