Abstract In this paper we revisit the idea of measuring the magnetic dipole moments of the charm baryons and, in particular, of Λ c + by studying the spin precession induced by the strong effective magnetic field inside the channels of a bent crysta

Coherent effects in the ionization loss of ultrarelativistic electron ensembles (bunches) are studied on the basis of perturbation theory of quantum mechanics. These effects originate from the interference of the electrons’ proper electric fields w

The process of diffracted x-ray transition radiation by a high-energy “half-bare” electron in a crystalline target is considered in Bragg geometry. The electron is supposed to appear in the mentioned state, in which the field around it is signifi

We consider the possibility of observation of the coherent radiation suppression effect occurring at motion of GeV positrons in the field of (110) crystal atomic planes of thin Si crystals, and its oscillatory dependence on crystal thickness. The par
