... The angular part of the wave functions will be the SAME, i.e. Y (ϑ, ϕ). Therefore we can again classify the orbitals as 1s, 2s, 2p0 , 2p1 , 2p−1 , etc. The radial part: R(r) will differ, since the potential is different here form that of the H atom: since it is not a simple Coulomb-potencial, the de ...
