Das Frequenzspektrum von ungeordneten Ketten in der Konfigurationsmittel-Approximation
Abstract
It is shown, that the spectrum following from the configurational average of the eigenfrequency equation is positive and normalized. It satisfies the long-wave-approximation and the Rayleigh-theorem. The frequency distribution has been calculated for mass ratios μ=4/5, 2/3, 1/2, 1/3, 1/10 and concentrations q=1/10, 3/10 ... 9/10 and has been compared with the selfconsistent field approximation of the spectrum. © 1965 Springer-Verlag.
