Precision tests of QED are limited by our knowledge of the hadronic effects. In particular, predictions for the Lamb shift are suffered from a bad knowledge of the nuclear structure. One can reverse the problem and to determine nuclear parameters from spectroscopy. Studying the Lamb shift in ordinary and muonic hydrogen, values of the proton charge radius have been derived. The ordinary-H...

The contradiction currently exists in the results of proton electromagnetic form factors measurements. More accurate calculation of radiative corrections to electron-proton elastic scattering cross section is one of the possible solutions of this problem. Here we consider a potential contribution of Delta(1232) resonance to real radiative corrections. The effect is found to be small for past...

The large photon flux of heavy-ion beams at high energy results in
electromagnetic processes with large cross sections. Processes which
change the magnetic rigidity of the primary beam produce secondary
beams. The knowledge of the cross section of these reaction channels
is of great interest since they contribute to the finite lifetime of
the heavy-ion beam. Electromagnetic excitation...

"Effects of strong electromagnetic field in ultra-relativistic
heavy-ion collisions"
Abstract:
In collisions of relativistic nuclei of gold (the RHIC collider)
or lead (the LHC collider) electric and magnetic fields may exceed
by several orders of magnitude the critical Schwinger field, but
these fields act during a very short time. In...

QED processes in the field of a heavy atom are important in different area such as atomic physics, high energy physics, astrophysics and others. These processes are describe interaction of charged particles and photons with matter. Bremsstrahlung and particle-antiparticle photoproduction in the electric field of a heavy nucleus or atom play a dominant role when considering electromagnetic...
