Nettet12. sep. 2024 · The finite lifetimes of these states can be deduced from the shapes of spectral lines observed in atomic emission spectra. Each time an excited state decays, the emitted energy is slightly different and, therefore, the emission line is characterized by a distribution of spectral frequencies (or wavelengths) of the emitted photons. Nettet8. feb. 2024 · We estimate a fundamental radiative linewidth of 1.54 ± 0.17 meV, owing purely to finite radiative lifetime in the absence of nonradiative dephasing processes. As a direct consequence of the large radiative limit, we find a surprisingly large ( ∼ 0.27 meV ) linewidth broadening due to zero-point energy of acoustic phonons.
