    "abstract": "An elementary treatment of the Dirac equation in the presence of a three\ndimensional spherically symmetric delta potential is presented. We show how to\ncalculate the cross section using the relativistic wave expansion method for a\none delta potential and two concentric delta potentials. We compare our results\nwith the cross section calculated in the Born approximation.",
