Unexpected Delta-Function Term in the Radial Schrodinger Equation
Anzor Khelashvili, Teimuraz Nadareishvili
Careful exploration of the idea that equation for radial wave function must be compatible with the full Schrodinger equation shows appearance of the delta-function while reduction of full Schrodinger equation in spherical coordinates. Elimination of this extra term produces a boundary condition for the radial wave function, which is the same both for regular and singular potentials.
