Figure 4
The absorption spectra obtained from the Ni foil with (i) 1 scan, (ii) 10 scans, (iii) 100 scans, (iv) 1000 scans, (v) 10000 scans and (vi) 10000 scans with odd and even channels averaged. The data sets are offset vertically by 0.1 units for clarity. Acquisition times per scan are It = 250 µs and I0 = 100 µs. |
