Phys. Rev. B 29, 1048–1049 (1984)Optimization of data end points and taper width in extended absorption fine-structure analysisReceived 20 July 1983; published in the issue dated 15 January 1984 The dependence of deduced interatomic spacing and inner potential on the lower and upper limits of integration, k1 and k2, as well as the taper width D, was studied for extended absorption fine structure using sinusoidal model data. The optimal values are achieved when 2(k1+k2)R or 2(k2-k1-D)R equals an odd half-integral multiple of π (rather than when 2k1R and 2k2R are integral multiples of π), where R is the spacing. Analytic approximations are used to elucidate numerical computations. Optimization of D is also discussed. © 1984 The American Physical Society URL:
