## Abstract During the last few years a number of experimental techniques have been developed with the general purpose of obtaining structural information from EXAFS‐like spectra without resorting to synchrotron radiation. The aim of this paper is to show the physical principles and the experimenta

Abstract
The short‐range order contribution to the internal energy in Ising models is calculated in an effective type treatment. However, the method incorporates correlation effects through a phenomenological approach and the results obtained are an improvement over other effective field calculations when compared with exact (z = 4) or series results (z = 6).
