Angular distribution and linear-polarization of X-rays induced by radiative electron capture process

Abstract

By using the Born approximation, calculations are made for photon angular distributions of the radiative electron capture to the L shell and for linear polarization correlations of photons induced by the radiative electron capture to the K shell for relativistic incident velocities. The angular distributions have minimum value in the forward directions and maximum values in the backward directions relative to 90°. This behavior becomes significant with increasing velocity. The polarization correlation of the emitted photon represents the crossover feature in the case of relativistically high energy impacts.
