On the problem of relativistic particles motion in strong magnetic field and dense matter
We consider a problem of electron motion in different media and magnetic
field. It is shown that in case of nonmoving medium and constant homogenious
magnetic field the electron energies are quantized. We also discuss the general
problem of eigenvectors and eigenvalues of a given class of Hamiltonians. We
examine obtained exact solutions for the particular case of the electron motion
in a rotating neutron star with account for matter and magnetic field effects.
We argue that all of these considerations can be usefull for astrophysical
applications
The experimental study of the surface current excitation under the influence of a relativistic electron electromagnetic field
The problem of the surface current excitation in a conductive targets by a
relativistic electron electric field as the origin of such radiation mechanisms
as diffraction and transition radiation of relativistic electron was considered
in frame of both surface current and pseudo-photon methods. The contradiction
between these viewpoints in respect to the surface current on the target
downstream surface necessitated the experimental test of this phenomenon. The
test performed on electron beam of the 6 MeV microtron showed, that not any
surface current is induced on the target downstream surface under the influence
of a relativistic electron electromagnetic field in contrast to the upstream
surface. This is important implication for the understanding of the forward
transition and diffraction radiation nature.Comment: Was Presented at the symposium Channeling 2008 (Charged and Neutral
