Существующие 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 членов в формулу для энергетического разрешения, без их связи с конкретными характеристиками сцинтилляционного детектора, что не позволяет корректно определить собственное энергетическое разрешение сцинтилляционного детектора. Собственное энергетическое разрешение сцинтилляционного детектора наиболее правильно определить как тот неустранимый предел, который может быть достигнут, когда все параметры детектора достигают своих предельных значений и их флуктуации отсутствуют. На основании микроскопической стандартной теории сцинтилляционных детекторов показано, что собственное энергетическое разрешение будет определяться нелинейностью световыхода, и флуктуациями числа электронно-дырочных пар.</p></abstract><trans-abstract xml:lang="en"><p>At present, the intrinsic energy resolution of a scintillation detector is understood by many authors in different ways. The existing formulas for energy resolution differ not only in names, but also in the physical meaning of the processes they take into account. The main drawback of all 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. The intrinsic energy resolution of a scintillation detector is most correctly defined as the unavoidable limit that can be reached when all the parameters of the detector reach their limiting values without their fluctuations. On the basis of the microscopic standard theory of scintillation detectors, it is shown that the intrinsic energy resolution is determined by the light yield nonlinearity and fluctuations in the number of electron–hole pairs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сцинтилляционный детектор</kwd><kwd>фотодетектор</kwd><kwd>энергетическое разрешение</kwd><kwd>собственное энергетическое разрешение</kwd><kwd>световыход</kwd><kwd>светосбор</kwd><kwd>нелинейность световыхода</kwd><kwd>фактор Фано</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scintillation detector</kwd><kwd>photodetector</kwd><kwd>energy resolution</kwd><kwd>intrinsic energy resolution</kwd><kwd>light yield</kwd><kwd>light collection</kwd><kwd>light yield nonlinearity</kwd><kwd>Fano factor</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">Dorenbos P. et al. // IEEE Trans.
