Structure Model of a One‐Dimensional Disordered System with Short‐Range Order

An ensemble of disordered linear chains is described by a probability density distribution without making use of the laws of thermodynamical equilibrium statistics. Short‐range order is present in the system, because the position of an arbitrary particle depends on the location of the nearest neighbours. The nearest neighbour distance statistics is assumed to be of the Gaussian type. All correlation functions are calculated for finite and infinite systems. The superposition approximation is found to hold rigorously. The pair correlation is of fundamental importance for the system. The radial pair distribution function is investigated thoroughly. The configurational entropy of the system is calculated and discussed.
