I(h) function calculator
This Javascript calculates the scattering curve I(h) of models consisting of up to 8 spheres with the same radius and optionally different electron densities and different x/y/z coordinates using the Debye-formula in reciprocal space. Enter the number of spheres, their common radius R, their coordinates x(i), y(i), z(i) and their electron-densities c(i). For N points the scattering curve from h = 0 to hmax with a scaling factor f (optionally also in a logarithmic intenisty scale) will be calculated. The values are listed in h vs I(h) or vs log(I(h)) in arbitrary units and can be copied and pasted from the window into any text-file for further processing and graphical displaying.
