摘要：
The specified constant 4-vector field reproducing the spherically symmetric stationary metric of a cold dark matter halo in the region of flat rotation curves results in a constant angle of light deflection at small impact distances. The effective deflecting mass is a factor pi/2 greater than the dark matter mass. The perturbation of deflection picture due to the halo edge is evaluated.
