Abstract

Collisions of antiprotons with bare uranium nuclei are studied for scattering angles nearby 180$^{\circ}$ in the framework of relativistic theory. The Coulomb glory phenomenon is investigated at energies of the antiprotons in the range 100 eV to 2.5 keV. The vacuum polarization effect and the anomalous magnetic moment of the antiproton are taken into account. The estimations of possible influence of such effects as radiative recombination and antiproton annihilation are given.
