Слагаемые, входящие в формулы для энергетического разрешения, различаются не только названиями, но также и физическим смыслом учитываемых ими процессов. Главный недостаток всех существующих теорий сцинтилляционных спектрометров заключается в необоснованном введении различных слагаемых в формулу для энергетического разрешения, без их связи с конкретными характеристиками сцинтилляционного детектора. Такой подход является не только неправильным, но и контрпродуктивным, поскольку не позволяет сравнивать результаты, полученные различными научными группами. В данной работе, на основании стандартной теории сцинтилляционных спектрометров с несколькими фотодетекторами, проведен анализ недостатков существующих теорий. Показано, что только формулы стандартной теории для произвольных моментов функции распределения выходных сигналов фотодетекторов сцинтилляционного спектрометра служат надежной основой для связи теоретических и экспериментальных исследований в области физики сцинтилляционных детекторов.</p></abstract><trans-abstract xml:lang="en"><p>   At present, scientists propose different formulas for the energy resolution of scintillation spectrometers, which sometimes contradict each other. The terms included in the formulas for the energy resolution differ not only in their names but also in the physical meaning. The main drawback of all of these theories of scintillation spectrometers is the unjustified introduction of different terms into the formula for the energy resolution without considering their connection with the specific characteristics of the scintillation detector. This approach is not only wrong but also counterproductive, since it does not allow comparison of the results obtained by different scientific groups. In this work, the drawbacks of the theories are analyzed on the basis of the standard theory of scintillation spectrometers with several photodetectors. It is shown that only the formulas of the standard theory for arbitrary moments of the output signal distribution function of the photodetectors of a scintillation spectrometer serve as a reliable basis for linking theoretical and experimental researches in the field of scintillator physics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сцинтилляционный детектор</kwd><kwd>фотодетектор</kwd><kwd>энергетическое разрешение</kwd><kwd>световыход</kwd><kwd>нелинейность световыхода</kwd><kwd>светосбор</kwd><kwd>фактор Фано</kwd><kwd>ковариации сигналов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scintillation detector</kwd><kwd>photodetector</kwd><kwd>energy resolution</kwd><kwd>light yield</kwd><kwd>light yield nonlinearity</kwd><kwd>light collection</kwd><kwd>Fano factor</kwd><kwd>covariance between signals</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Breitenberger E. // Progr.
