Nature of problem:
SCR2 calculates energy levels and wave functions of the rotational symmetric Schrodinger equation for a given potential using a simple and accurate method.

Solution method:
An iterative procedure for getting upper and lower bounds to energy values of the radial Schrodinger equation is given. A numerical integration procedure together with convexity arguments and the nodal theorem for wave functions is used.

Running time:
5 sec for one bound state, note: the running time depends strongly on the desired accuracy.
