Table 1388a lists the main edges of Y used in EELS analysis. The features of the Y M4,5 edges are complicated due to the 3d → 4f transitions.

In order to record the signals of Y together with other elements in a single EEL spectrum, a proper edge of Y should be selected. For instance, Table 1388b lists some application examples of Y edges used in the particular cases.
