  We critically reexamine the gravitational scattering of scalar particles on a
global monopole studied recently. The original investigation of Mazur and
Papavassiliou is extended by considering different couplings of the scalar
field to the space-time curvature and by varying the dimension of the
space-time where the Klein-Gordon (KG) field lives. A universal behavior of the
leading term in the scattering amplitude as a function of this dimension is
revealed.
