It carries more momentum as a consequence of increased relativistic mass, which comes from energy imparted to the beam. However I think the momentum transfer would be even greater if that energy had been radiated directly rather than imparted to the particle beam. However it may not make much difference for a particle beam traveling at nearly light speed anyway, and acceleration of a particle beam may be technically easier to achieve.
