BASIS SPLINE COLLOCATION METHOD FOR SOLVING THE SCHRODINGER EQUATION IN AXILLARY SYMMETRIC SYSTEMS

摘要

We use basis spline collocation to solve the Schrodinger equation on a lattice for axially symmetric systems, with and without spin. The focus of the present work is on systems which have continuum states, weakly bound states, or strong spin-orbit coupling, since these are the most difficult to solve on the lattice. A brief overview of the basis spline collocation method is included which concentrates primarily on those aspects of the theory which are relevant to its application in cylindrical coordinates. To demonstrate the method, we solve several model problems selected from the fields of atomic and nuclear physics. (C) 1996 Academic Press, Inc. [References: 25]
