Sample for Small Angle X-ray Scattering - hard spheres in thin solution, mono disperse.
Author: E. B. Knudsen, P. Willendrup, K. Lefmann, L. Arleth
Origin: DTU Fysik
Sample for use in a SAXS instrument, models hard, monodisperse spheres in thin solution.
The shape of the sample may be a filled box with dimensions
xwidth, yheight, zdepth, a cylinder with dimensions radius and yheight,
a filled sphere with radius R.
Example: Saxs_spheres(R = 20, Phi = 1e-3, Delta_rho = 0.6, sigma_abs = 50, xwidth=0.01, yheight=0.01, zdepth=0.005)
Parameters in boldface are required;
the others are optional.
