An expression is derived for the variance taking into account exchange effects, and numerical estimates of the average excitation energy and variance are made based on the non-relativistic Roothaan–Hartree–Fock method and the relativistic Dirac–Hartree–Fock method implemented in the General Relativistic Atomic Structure Package (G<span>rasp</span>2018).
