In 1953, Landau and Pomeranchuk showed [1] that multiple scattering of ultrarelativistic electrons on atoms of the medium can lead to suppression of bremsstrahlung in the soft part of the spectrum compared to the predictions of the Bethe-Heitler theory. A quantitative theory of this effect was later developed by Migdal [2]. The region of the radiation spectrum in which...
An investigation into the stochastic deflection of high-energy charged particles in a bent crystal was conducted at the extracted lines of the CERN Super Proton Synchrotron. Specifically, we examined the mechanism of relaxation of axially confined 400 GeV/c protons to planar channeling in a bent crystal. The experimental results were critically compared to computer simulations and analytical...
Crystalline materials differ from amorphous ones in the presence of periodicity in the arrangement of atoms. This periodicity leads to the possibility of observing orientation effects when high-energy charged particles pass through crystals. Such effects become possible when the angle between the particle's momentum and the crystalline atomic axis or plane becomes small. In this case, the...
It is well known that isospin symmetry is fulfilled to a good approximation in strong interactions, as confirmed in low-energy scattering experiments and in mass spectra of both light and heavy hadrons. In collisions of nuclei with an equal number of protons and neutrons, isospin symmetry imposes that the number of produced charged kaons should equal the number of neutral ones. The NA61/SHINE...
