The full relativistic description of the bremsstrahlung process in a charged particle-atom collision

Abstract

Formalism for the full relativistic treatment of the spectral and angular distributions of the bremsstrahlung formed in collision of a charged particle with an atom is developed. Both leading mechanisms of the radiation formation, i.e. the ordinary and the polarizational bremsstrahlung, are incorporated into the scheme. Limiting cases of the general formulae are investigated in detail and it is demonstrated that the general formalism reproduces correctly the results of these simpler theories.
