Figure 6
The absorption coefficient β obtained from the spectrum in Fig. 5 in accordance with equation (1), and data from the CXRO database, on (a) a double logarithmic scale; (b) a linear scale; (c) a linear scale, zoomed beyond the absorption edge. The orange area shows the uncertainty (up to ±5%) associated with the C content in the range 1.2–2% and O in the range 0.3–0.6% (by atomic concentration). The blue line for Cx=0.015Oy=0.004 corresponds to the content of 1.5% C and 0.4% O inside the Be film. |
