It is also known as an electronic (de-)excitation or atomic transition or quantum jump.

The larger the energy separation of the states between which the electron jumps, the shorter the wavelength of the photon emitted.

The observability of quantum jumps was predicted by Hans Dehmelt in 1975, and they were first observed using trapped ions of mercury at NIST in 1986.

Electron transitions cause the emission or absorption of electromagnetic radiation in the form of quantized units called photons.

Their statistics are Poissonian, and the time between jumps is exponentially distributed. The damping time constant (which ranges from nanoseconds to a few seconds) relates to the natural, pressure, and field broadening of spectral lines.

However, in 2019 it was demonstrated that the evolution of each completed jump is continuous, coherent, deterministic, and reversible.
