Scattering and bound states for the Hulthén potential in a cosmic string background
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\'{e}n potential and obtain the phase …
