Spherical and cross-sectional correlation functions for solid cylinders 35 Å in radius and 300 or 1000 Å in length calculated from computationally generated scattering intensities. The cross-section correlation functions approach zero at the diameter (70 Å). Spherical correlation functions extend out to a distance equal to their length although for long cylinders its value is quite low for r much greater than the diameter of the cylinder. The slight difference between the cross-section correlation functions calculated for the cylinders 300 and 1000 Å in length is due to approximations required to estimate equatorial scattering at very small q. |
