  We calculate the angles of deflection of high speed particles projected in an
arbitrary direction into the Kerr gravitational field. This is done by first
calculating the light-like boost of the Kerr gravitational field in an
arbitrary direction and then using this boosted gravitational field as an
approximation to the gravitational field experienced by a high speed particle.
In the rest frame of the Kerr source the angles of deflection experienced by
the high speed test particle can then easily be evaluated.
