Dear Everyone,<br> I have tried to generate a USPP of Cs with electron configuration of [Xe]6s1, but now if I want to include the 5s and 5p states in the valence. How should I write the new configuration for the input file? i.e. now [Xe] can't be used as the core anymore, and I remember that the core has to be a noble gas, so if I include 5s 5p 6s states for the valence, then what will be done for the core? I really appreciate for all your help!<br>
