A new, generalized formulation is presented for the density of segments about the center of mass in random-flight chains having branched architectures. Numerical results axe obtained for linear chains and it is observed that the results attain the asymptotic limit for n = 01 in the same way as the d

โฆ Synopsis
Segment densities of comb and star branched random-flight chains hage been computed. It is found that the commonly used ~ussbn differs nrore s&nifiuntly for branched chains than for linear chains. The asymptotic results are also found to depend on the branching parameter.g.

Lifshitz has shown that the density of states of random systems becomes exponentially small near the band edge. We perform a detailed computation in a one-dimensional system and calculate the periodic prefactor of this essential singularity. The analysis is extended to the wavenumberdependent spectr
