The Mechanism Responsible for a Low Electrostatic Discharge Failure Threshold of an Output Buffer Circuit with Low Current Drive Capability

Abstract

The first-order Hartree-Fock (HF) equations for the ground state of atomic systems with 4 to 10 electrons are deduced from the corresponding unrestricted (UHF) equations given previously. The second-order HF energies are given exactly and the third-order energies very accurately. Each atom is treated as a special case of a general scheme. The third-order energy of lithium is calculated very accurately, completing Linderberg's calculation.The H F ground state energies of atoms with 3-10 electrons are shown to differ very little from the corresponding U H F energies previously given.The zero-and first-order expectation values of various operators are related to their corresponding U H F values.
