Study of resonances in the complex charge plane

Potential resonances are usually investigated either directly in the complex energy plane or indirectly in the complex angular momentum plane. Another formulation complementing these two approaches is presented in this work. It is an indirect algebraic method that studies resonance in a complex charge plane (Z-plane). The complex scaling (rotation) method is employed in the development of this formulation. A finite L-2 basis is used in the numerical implementation of the method.
