  By using a simple procedure the general solution of the time-independent
radial Schrodinger Equation for spherical symmetric potentials was made without
making any approximation. The wave functions are always periodic. It appears
two diffucilties: one of them is the solution of the equation E= U(r), where E
and U(r) are the total an effective potential energies, respectively, and the
other is the calculation of the integral of the square root of U(r). If
analytical calculations are not possible, one must apply numerical methods. To
find the energy wave function of the ground state, there is no need for the
calculation of this integral, it is sufficient to find the classical turning
points, that is to solve the equation E=U(r).
