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!
