Dear Tim,
That is described by the Laue interference function. The crystal
diffracts in Bragg directions (reflections) at small deviations of the
Bragg angle and in a small solid angle. They depend on lambda and
lambda^2 respectively, and integration over these angles brings a factor
lambda^3 in the diffracted intensity.
Best wishes,
Loes

Dear all,
according to Carmelo Giacovazzo's textbook (eq. 3.41 in the 1st edition), the
diffraction intensity I(hkl) scales with the wavelength cubed (lambda^3).
1) is there an easy rationale for this dependency?
2) does it hold over a wide range of energies?
3) does this also hold for neutrons or electrons as radiation source?
Thanks a lot for any helpful comment,
Tim
