Figure 12.

X-ray fluorescence emission spectrum showing Ge detector escape peaks. The data set is the same as that of Figure 9 but replotted with a wider energy range to show the escape peaks, plotted with counts per second (CPS) on the ordinate. X-rays impinging the detector with energies above the Ge K-edge (indicated) generate additional escape peaks due to loss of Ge X-ray fluorescence from the detector. The escape peaks corresponding to both the Ge Kα and the Kβ fluorescence lines are seen as echoes of the scatter peaks displaced to low energy by the Ge Kα and Kβ fluorescence energies, respectively. Data were collected on SSRL 9-3.
