Figure 1
Normalized intensity change as a function of dose for different exposure series. LF refers to the low-flux series (1 e Å−2 s−1), MF to medium-flux (5 e Å−2 s−1) and HF to high-flux (50 e Å−2 s−1). The normalized intensity change was found to be linear with dose as shown by least-squares fit to the data. |
