ground state
(redirected from ground states)

    Also found in: Medical, Encyclopedia 0.02 sec.
ground state
n.
The state of least possible energy in a physical system, as of elementary particles. Also called ground level.
ground state
The state of a physical system having the lowest possible potential energy. For example, an electron in the lowest energy orbital in a hydrogen atom is in a ground state. The ground state of a physical system tends to be stable unless energy is applied to it from the outside; states that are not the ground state have a tendency to revert to the ground state, giving off energy in the process. Compare excited state.
