Abstract

The first direct observation of radiative spectral transfer within an inhomogeneously broadened line (the R₁ line of ruby) is reported. As opposed to nonradiative transfer, the temperature dependence of the radiative process is consistent with exponential, in agreement with recent predictions. A temperature-independent, resonant process is also directly observed. The implication of these results for the concept of microscopic strain broadening is discussed.
