ground′ state`

the state of least energy of a particle, as an atom, or of a system of particles.

[1925–30]

ground state

The state of lowest possible energy, especially of subatomic particles. When subatomic particles, such as electrons and neutrons, are at a higher level of energy than their ground states, they emit radiation.
