Figure 2
The sin θ/λ dependence of the various scattering curves of oxygen (O0, O1−, O2−, OOC), corrected for the mean displacement parameter of the oxygen sites, used in the various SREFs of tremolite. Data are plotted from the coefficients for analytical approximation to the scattering factors listed for O0 and O1− in Table 6.1.1.4 of the International Tables for Crystallography (Brown et al., 2006), and for O2− as given by Hovestreydt (1983). OOC denotes optimization of O1− versus O2− and O0 versus O2− as obtained from SREF (see text for explanation). |
