The Fourier transform values are obtained by multiplying the integrated intensities by the correction factor C(h). The problem of calculating the correction factor for biological specimens which have a multilayered structure is treated. Allowance is made for the transverse size of the specimen, the disorientation in the specimen (ω), the divergence of the X-ray beam (![[epsilon]](/logos/entities/epsiv_rmgif.gif)
), the size of the repeating unit and the curvature of the sphere of reflection. The correction factor C(h) is given by C(h) = Ω[1 + 2γh2]1/2 exp (πδ2)exp (−Ω2[1 + 2γh2]), where γ = (ω2 + 2)/2(Ω2d2) and where Ω is the diameter of the hth order disc when ω = = 0. The formula for C(h) applies to specimens which remain stationary during the X-ray experiment.
