I(q) calculator of a lattice
This Javascript calculates the scattering curve of a 1D (lamellar), 2D (hexagonal), or several 3D (cubic) lattices, respectively. Enter the lattice type, the lattice spacing d-sp, the number n of peaks (1 to 8, peak c(0) at q=0 is not counted), their peak areas c(i) and the FWHM of the peaks. For Nr points I(q) from q = 0 to ~ n*2*Pi/dsp with a scaling factor f will be calculated. The values are listed in q vs I(q) in arbitrary units and can be copied and pasted from the window into any text-file for further processing and graphical displaying.
