Crystals present a uniquely simple environment for the investigation of strong
electromagnetic fields. When energetic charged particles are incident on crystals close to …

The observation of photons with energies above 1018 eV would open a new window in
cosmic-ray research, with possible impact on astrophysics, particle physics, cosmology and …

The features of electromagnetic processes are considered which connected with finite size
of space region in which final particles (photon, electron–positron pair) are formed. The …

È ben noto che le interazioni elettromagnetiche tra le particelle ad alta energia e la materia
allo stato solido subiscono modifiche sostanziali quando quest'ultima è cristallina ed i suoi …

The interaction of matter with radiation is a very broad subject and concerns almost every
area in physics1. Radiation as a diagnostic tool is used to investigate the properties of …

More than 80 years have passed since the first calculations of electron–nucleus
bremsstrahlung cross sections were published by Sommerfeld, for non-relativistic electrons …

At very high energies, pair production (γ→ e+ e-) exhibits many interesting features. The
momentum transfer from the target is very small, so the reaction probes the macroscopic …

Experimental results for the bremsstrahlung energy loss of 149, 207, and 287 GeV electrons
in thin Ir, Ta, and Cu targets are presented. For each target and energy, a comparison …

We review the problem of evaluating the energy loss of an ultrarelativistic charged particle
crossing a thermally equilibrated high-temperature e+ e− or quark–gluon plasma. The …
