Diffraction calculator of hexagonal unit cells

Enter number of shells in the 2D-hexagonal unit cell, their radius r, ther electron density c and their shape (circular or hexagonal). Radii should be increasing from 1 to 10 and overlapping of hexagons and circles should be avoided. The first 15 diffraction peaks of the hexagonal lattice will be calculated. The values are listed hk^2, q(hk), F(hk) and I(hk) - where the intensities I(hk) are the amplitudes squared F^2 divided by the multiplicity and by hk^2 - in arbitrary units and can be copied and pasted from the window into any text-file for further processing and graphical displaying.
