Abstract
For pt.I see ibid., vol.8, p.109 (1975). A method recently proposed by the authors for the calculation of the density of states n(E) of disordered systems is generalized and applied to one-dimensional alloys. The method approximates n(E) by the average of local densities of states of systems with very few disordered sites surrounded by a suitable ordered continuation of pseudoatoms. The authors obtain n(E) as a continuous function of E in the whole energy range, and the results compare extremely well with calculated histograms.Keywords
