I(h) function calculator
This Javascript calculates the scattering curve I(h) of concentric shell models (ellipsoid or cylinder). Enter the number of shells, the values for the radius R(i) and semi-axis Rz(i) (z is in the axis of rotation) and the corresponding electron-density c(i) (between R(i) and R(i-1)). For Nr points I(h) from h = h1 to hz with a scaling factor f will be calculated. P is the number of points used for the numerical integration. The values are listed in h vs I(h) or h 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.
