The radiative decay from an excited triplet state back to a singlet state is known as phosphorescence.
2.
This level likewise has a fast, non-radiative decay "'Rb "'into the ground state.
3.
The radiative decay rate \ Gamma _ { rad } is inversely proportional to the lifetime \ tau _ { 21 }:
4.
These mesons are most often observed in proton-antiproton annihilation, radiative decays of vector mesons, and meson-meson scattering.
5.
In tungstate scintillators [ [ calcium tungstate | ] ] and [ [ cadmium tungstate | ] ] the emission is due to radiative decay of self-trapped excitons.
6.
The relatively high, compared to lanthanides, non-radiative decay rates in Es 3 + were associated with the stronger interaction of f-electrons with the inner Es 3 + electrons.
7.
Since the Auger effect is not the only mechanism available for atomic relaxation, there is a competition between radiative and non-radiative decay processes to be the primary de-excitation pathway.
8.
Where \ Gamma _ { tot } is the total decay rate, \ Gamma _ { rad } is the radiative decay rate and \ Gamma _ { nrad } the nonradiative decay rate.
9.
Where N ( 0 ) is the initial number of light sources in the excited state, t is the time and \ Gamma _ { rad } is the radiative decay rate of the transition.
10.
Where k _ \ text { ET } is the rate of energy transfer, k _ f the radiative decay rate, and the k _ i are the rate constants of any other de-excitation pathways.
