energy level

n.
1. The energy characteristic of a stationary state of a physical system, especially a quantum mechanical system.
2. The stationary state of a quantum mechanical system. In both senses also called energy state.

energy level

n
1. (General Physics) a constant value of energy in the distribution of energies among a number of atomic particles
2. (General Physics) the energy of a quantum state of a system. The terms energy level and energy state are often used loosely to mean quantum state. This is avoided in precise communication

en′ergy lev`el


n.
one of a quantized series of states in which matter may exist, each having constant energy and separated from others in the series by finite quantities of energy.
Also called en′ergy state`.
