Relative Fisher information of hydrogen-like atoms
The relative Fisher information is a measure of distance between two probability densities. We calculate it for the electron orbitals of hydrogen-like atoms by taking 1s state as the reference orbital. We find that the measure decreases as the principal quantum number increases, indicating that the electron cloud of excited states in radial direction becomes close to the one of 1s orbital.
