Remarks on the Boundary conditions of the Radial Schrodinger
... Schrodinger equation if and only if the boundary condition u ( 0 ) = 0 is fulfilled. The radial equation (1) together with boundary condition (12) is equivalent to the full Schrodinger equation (2). Some comments are in order now: Equation for R ( r ) has its usual form.
