Hi, With DFT+U, it is usually possible to stabilize many different electronic states for f-systems. If you don't already know this paper, then it may be useful. https://journals.aps.org/prb/pdf/10.1103/PhysRevB.79.235125

I guess (if I have understood correctly) this is correspond to the configurations of no any electrons in spin-up and spin-dn. But I am dealing with a Uranium compound and I am not sure this is acceptable? If I need to check metastable state what I have to do? I appreciate any help to understand this. Thank you for your time Prasad
