<i>Ab initio</i> QED calculations in diatomic quasimolecules

We present a theoretical approach for ab initio calculations of the one-loop QED corrections to energy levels heavy diatomic quasimolecules. This is based on partial-wave expansion molecular wave and Green's functions in basis monopole solutions, written spherical coordinates. By using so-generated functions, we employ existing atomic-physics techniques evaluate self-energy vacuum-polarization corrections. In order illustrate application our method, perform detailed Dirac 1${\ensuremath{\sigma}}_{g}$ ground state homonuclear ${\mathrm{U}}_{2}{}^{183+}$ heteronuclear U-${\mathrm{Pb}}^{173+}$ Bi-${\mathrm{Au}}^{161+}$
