Description
In collisions of very heavy ions ( Z 1 + Z 2 > 172) molecular electronic orbitals are formed. Generalized Hartree-Fock equations for this case are derived from field theoretic principles. It is shown that the lowest ground state (i.e. the vacuum) becomes charged for Z > Z cr and R < R cr . If the K -shell is vacant, positron production sets in. The energy distribution of the positrons and the cross-section for this process are calculated.
