Zur Theorie der Dispersion in Gasen und Dämpfen

Dipole Interaction and Scattering of Light

“…An exact solution of this problem is hopeless; therefore, system [4] is solved approximately. 3 The absolute value of the polarization a in accordance with [5] reaches the order of magnitude of the cube of the wavelength of light X only in the immediate vicinity of precise resonance (co = co 0 ); for distances co -co 0 greater than the real line width modulus a is smaller than X 3 and then decreases rapidly. Therefore, for frequencies of incident light which are sufficiently removed from reissuance segment I can be introduced in such a manner that…”

“…It is pointed out that in the approximate computation of integrals terms of the order of magnitude of (l/X) 3 are neglected in relation to the ones taken into account. Taking [5] into account, [24] can be expressed in the following terms to a sufficient degree of accuracy:…”

“…In this case Reiche's work (3), which develops the theory of the scattering of light for low gas densities, is used to a certain extent.…”

“…Substitution of Eq. [3] in [2], taking [1] into account, gives the following system of algebraic equations for the determination of q:…”

“…flux and due to the axial symmetry the output of the receiver remains unchanged during the rotation of the latter around the 00 axis). The given receiver-photometer (2) (symmetrical receiver of light energy for a hemispheric flux) satisfies all requirements discussed at the beginning of the paper and is simpler in construction in comparison with the device described in the work by P. L. Tea and H. D. Baker (3).…”
