If only one of these gamma-rays escapes while the other is completely absorbed in the detector, 511 keV will be lost from the detector. This results in a separate peak in the spectrum representing E g -511 keV, called the single escape peak. If both annihilation gamma-rays escape this gives rise to the double escape peak at E g -1022 keV.
