Converting Sabine absorption coefficients to random incidence absorption coefficients

The Journal of the Acoustical Society of America, 2013
Absorption coefficients measured by the chamber method are referred to as Sabine absorption coefficients, which sometimes exceed unity due to the finite size of a sample and non-uniform intensity in the reverberation chambers under test. In this study, conversion methods from Sabine absorption coefficients to random incidence absorption coefficients ...

Absorption Coefficients for Exciton Absorption Lines

Physical Review, 1957
The absorption coefficient for excitons is calculated in the effective-mass approximation. The coefficient is shown to be decreased over what one would expect for a collection of free atoms by the factor ${\ensuremath{\epsilon}}^{\ensuremath{-}1}{(\frac{{a}_{0}}{{a}_{B}})}^{3}$, where $\ensuremath{\epsilon}$ is the dielectric constant and $\frac{{a}_{0}
