resonance transition

resonance transition

A change in the energy state of an atom, involving an electron jump from the ground state to a higher energy level, leading to excitation, or a return to the ground state from an excited state. This produces a resonant absorption or emission line in a spectrum. See also ultraviolet astronomy.

Experiments exploiting other ideas for measuring the energy scale, that is, the energy differences between quantum states, are proposed by observing resonance transitions induced by a magnetic field [16-19] and mechanical vibrations [20].
