Abstract: | Any atom—excess-electron system confined to an arbitrary finite region of space that is free of external fields and which can be characterized by a non-relativistic spin-free hamiltonian has, in the limit of infinite nuclear mass of the atom, an exact ground-state expectation value of the atom—electron interaction hamiltonian that is negative-definite. |
