Under the conditions that the wavelength of a particle is much larger than its radius of central mass, and the Schwarzschild field is weak, the scattering of a particle has been studied by many researchers. They obtained that scalar and vector particles abide by Rutherford's angle distribution by using the low level perturbation method and the scattered field's approximation in a weak field. The scattering cross section of a photon coincides with the section in Newton's field of point mass. We can obtain the photon's polarization effect by calculating the second-order perturbation in the linear Schwarzschild field. This article discusses the scattering and absorption of a particle by a black hole involving a global monopole by using the aforesaid method.
