Figure 7
Precession electron-diffraction patterns (left) and kinematic simulations (right) of the [100], [001] and [110] zone axes. The simulations are calculated using the sarrabusite model obtained with SIR2008. The precession angles are 4° for [100] and 3.5° for [010] and [110]. The arrows in the [100] zone axis indicate reflection rows belonging to the first and higher-order Laue zones which arise since the a parameter is quite long.  [article HTML]
