Why is there an upper limit to the number of observed orders?
A thin crystalline layer has to be characterized in terms of lattice constant (roughly 0.56 nm, twice the atom’s distance). You try to apply the technique of x-ray diffraction based on the Kß-line of 42Mo (ignore any screening effects). At which diffraction angle(s) can we expect a signal?
