WebMar 1, 2016 · $\begingroup$ The efficiency changing from peak to peak is very common, but changing enough to matter over the width a single peak is fairly rare for precision devices like germanium detectors. If you have NaI detector I'd be more worried about that. The acceptance issue is similar: it can change significantly over the range of a typical …
