The instrumental broadening of the diffraction peaks depends upon the time resolution dt/t, where dt is the error or uncertainty in time t. Show that dt/t is related to the angular resolution of the detector, d0, by: dt/t = cot0.d0 Hence explain why large detector 20 angles are preferred for high resolution experiments.
