Angular-distribution and linear-polarization correlation of photons induced by the relativistic radiative electron-capture process

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 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 an increase of velocity. The polarization correlation of the emitted photon represents the crossover feature in the case of relativistically high energy impacts.
