Both rcsfgenerate and jjgen seem unable to cope with more than 20 relativistic orbitals (5f and beyond) in the reference configuration. Are there any work arounds with this? For example: 1s(2,i)2s(2,i ...

Since there are nine m l values, there are nine orbitals with n = 3. The total number of orbitals for a given n value is n2 . The atom’s energy levels, or shells, are given by the n value. The n = 1 ...
