Abstract

Integrated absolute full energy peak efficiency (IAFEPE) is a measure of photon registration efficiency using the γ-ray spectrometry method. We have derived appropriate formulas and theoretical explanations of IAFEPE for the first time. IAFEPE is a definite integral (Riemann integral) of the photon registration efficiency function within the detection energy range. IAFEPE, along with associated quantities such as mass integrated absolute full energy peak efficiency and surface integrated absolute full energy peak efficiency, allows for the quantitative validation of measurement conditions.
