Motion around a global monopole

The motion of test particles and light rays in the perturbed gravitational field around a global monopole is studied. The metric of the monopole was p reviously obtained by solving the linearized semiclassical Einstein equatio ns (Hiscock). The bending of light ray passing by such a monopole has contr ibutions from the conical object as well as from the perturbed terms. The p ossibility of trapping particles in the perturbed gravitational field is al so discussed.
