Figure 17
A series of stationary profiles, using the Bragg–Brentano geometry, of the Si sample described in the text. The experiments were measured at 0.5° intervals over 10° in φ. The profiles appear to exist in two distinct forms, a general `background' (smooth hump) and a spiky region superimposed, thought to be associated with `non-Bragg' and `Bragg' contributions, respectively. The spikes appear and disappear within similar angular ranges in φ as predicted from the calculations leading to Fig. 14(b). |
