n.
The state of least possible energy in a physical system, as of elementary particles. Also called ground level.

ground state

n
(General Physics) the lowest energy state of an atom, molecule, particle, etc. Compare excited4

ground′ state`


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

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.
