One-center calculations of the electron-positron pair creation in low-energy collisions of heavy bare nuclei
Eur. Phys. J. D, 72 :115 (June 2018)
Abstract:
The probabilities of bound-free electron-positron pair creation are calculated for head-on collisions of bare uranium nuclei beyond the monopole approximation. The calculations are based on the numerical solving of the time-dependent Dirac equation in the target reference frame with multipole expansion of the projectile potential. In addition, the energy dependence of the pair-creation cross section is studied in the monopole approximation.
