AGONY

(Kronig, 1931) or a short-range order theory in terms of scattering by neighboring atoms (Kronig, 1932, Hartree, et al. 1934, Shiraiwa, et al. 1958) is more appropriate. A major source of the confusion was that quantitative comparison between theory and experiment was difficult if not impossible at the time.
