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. Graphical abstract

Electron-positron pair production in slow collisions of heavy nuclei beyond the monopole approximation
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
How to Observe the Vacuum Decay in Low-Energy Heavy-Ion Collisions.
It is shown that the vacuum decay can nevertheless be observed via impact-sensitive measurements of pair-production probabilities and the possibility of such an observation is demonstrated using numerical calculations of pair production in low-energy collisions of heavy nuclei.
Electron-Positron Vacuum Instability in Strong Electric Fields. Relativistic Semiclassical Approach
Instability of electron-positron vacuum in strong electric fields is studied. First, falling to the Coulomb center is discussed at $Z>137/2$ for a spinless boson and at $Z>137$ for electron. Then,
How to access QED at a supercritical Coulomb field
In slow collisions of two bare nuclei with the total charge number larger than the critical value, Zcr≈173, the initially neutral vacuum can spontaneously decay into the charged vacuum and two
Stringent tests of QED using highly charged ions
The present status of tests of QED with highly charged ions is reviewed. The theoretical predictions for the Lamb shift and the transition energies are compared with available experimental data.


Electron-positron pair creation in low-energy collisions of heavy bare nuclei
A new method for calculations of electron-positron pair-creation probabilities in low-energy heavy-ion collisions is developed. The approach is based on the propagation of all one-electron states via
Positron production in crossed beams of bare uranium nuclei.
Positron creation in crossed-beam collisions of high-energy, fully stripped heavy ions is investigated within the coupled-channel formalism and the positron spectrum is shifted towards higher energies because of the absence of electron screening.
Positron creation probabilities in low-energy heavy-ion collisions
AbstractThe previously developed technique for calculation of ionization probabilities in low-energy heavy-ion collisions [A.I. Bondarev et al., Phys. Scr. T156, 014054 (2013)] is extended to
Theory of positron production in heavy-ion collisions
Collisions of very heavy ions at energies close to the Coulomb barrier are discussed as a unique tool to study the behavior of the electron-positron field in the presence of strong extemal
Positron production in collision of heavy nuclei
Abstract.We consider the electromagnetic production of positron in the collision of slow heavy nuclei, with the simultaneously produced electron captured by one of the nuclei. The cross-section of
Calculation of electron-positron production in supercritical uranium-uranium collisions near the Coulomb barrier
The time-dependent Dirac equation was solved for zero-impact-parameter bare U-U collisions in the monopole approximation using a mapped Fourier grid matrix representation. A total of 2048 states
Treatment of U92+–U91+ collisions in spherical co-ordinates: going beyond the monopole approximation
Recently, a new approach has been developed to treat the time-dependent two-centre Dirac equation within our group. This method generates basis wavefunctions describing an electron in the field of
Magnetic Splitting of Quasimolecular Electronic States in Strong Fields
The heavy-ion motion in sub-Coulomb collisions generates extreme magnetic fields. The hyperfine splitting of the spin-\textonehalf{} quasimolecular electronic states in U + U is found to reach 10% of
