This system is allowed to freely rotate in 3d space about its center of mass. Then, the probability of an electron being within a certain area can be assessed. It must be noted that the appearance of the delta function in the laplace equation was discussed also in article 6, where the difference between spaces. Again, for a given the maximum state has no radial excitation, and hence no nodes in the radial wavefunction. You can give the radial part of the wave function the name r nl r, where n is a quantum number corresponding to the quantum state of the radial part of the wave function and l is the total angular momentum quantum number.
