The dielectric constant of a gas of resonant atoms is found for frequencies corresponding to the transition between a zero-momentum ground state and a unity-momentum excited state; pair collisions involving resonance energy transfer are assumed to make the main contribution. The interaction between the...
Dielectric Constant of Simple Gases 来自 Semantic Scholar 喜欢 0 阅读量: 30 作者:Levine,Howard B 摘要: A general expression for the second dielectric virial coefficient for a rare gas is derived by a simple cluster method. The resulting formula requires for its evaluation a knowledge of the ...
Dielectric-constant gas thermometry can be used both for primary and interpolating thermometry as well as for the determination of the Boltzmann constant. These applications are evaluated in detail on the basis of a reanalysis of the results obtained at PTB. The reanalysis allows to estimate the ...

When surface plasmons exist, the real part of the metal dielectric constant must be negative and its magnitude must be greater than that of the dielectric. This condition is satisfied in the wavelengths range of IR-visible lights for air/metal and water/metal interfaces, where the real part ...
