Dear NWChem developers and users,
I am doinc calculation for fraction occupation number for C. If " fon partial 3 electrons 2.0 filled 2" then i should get the exact ground state energy of C atom which is 37.845. But i don't. What is the problem? Please, someone, tell me.

title "carbon atom"
start carbon_fon
geometry units angstrom nocenter
