B-SPLINES : A POWERFUL AND FLEXIBLE NUMERICAL BASIS FOR THE CONTINUUM SPECTRUM OF THE SCHROEDINGER EQUATION. AN APPLICATION TO HYDROGENIC ATOMIC SYSTEMS

摘要

We present a method for the accurate calculation of the complete spectrum of the Schrddinger equation in terms of B-splines polynomial basis. The method is capable to represent numerically the bound and continuum spectrum of complex atomic systems. The theoretical method is discussed, and an application to hydrogenic hamiltonian is given.
