looking for atomic energy level database

einstein1921

Hello,everyone! I want to know if there is database which can tell me the energy level diagram of atom. I have consulted NIST Atomic database,but I can't find energy level diagram. so anybody can help me ? I WANT to get the energy leverl diagram like hydrogen atom in modern books(potential energy is 0 at infinite) Thank you!
ps: I want to get the energy level diagram of Cd
I want to know the energy of 1s electron if we set infinite potential energy to zero!

Usually it can be calculated using quantum chemistry softwares like Gaussian. Without software it is tough.

Thank you for your reply! take Cd example, I calculate the atomic orbital with Gaussian! there are 24 energy level,but I don't know which energy level is 3s, which is 4d and so on! would you please to help! Thank you!
