Abstract

Electron-positron pair production in low-energy collisions of heavy nuclei is considered beyond the monopole
approximation. The calculation method is based on the numerical solving of the time-dependent Dirac equation
with the full two-center potential. Bound-free and free-free pair-production probabilities as well as the energy
spectra of the emitted positrons are calculated for the collisions of bare uranium nuclei. The calculations are
performed for collision energy near the Coulomb barrier for different values of the impact parameter. The
obtained results are compared with the corresponding values calculated in the monopole approximation.
