In this work we study the Dirac equation with vector and scalar potentials in the spacetime generated by a cosmic string. Using an approximation for the centrifugal term, a solution for the radial differential equation is obtained. We consider the scattering states under the Hulth,n potential and obtain the phase shifts. From the poles of the scattering S-matrix the states energies are determined as well.
