Мотивацией для подготовки эксперимента послужили новые экспериментальные данные о фотовозбуждении спиновых изомеров среднетяжелых ядер, где были получены косвенные указания на изменение мультипольности фотопоглощения ядер вблизи порога. Настоявший эксперимент предполагает прямое изучение обнаруженных эффектов путем измерения полных сечений фотопоглощения на фотонном пучке. Моделирование выполнено по программе GEANT-4. Проведена оптимизация параметров установки и обоснован выбор детекторов для проведения измерений.</p></abstract><trans-abstract xml:lang="en"><p>An experiment to study total nuclear photoabsorption cross sections at the linear electron accelerator LUE-8-5 (INR, RAS) in the photon energy region of 5–10 MeV called the pygmy resonance is simulated. The motivation for the experiment is new experimental data on photoexcitation of spin isomers of medium-heavy nuclei, which indirectly indicate a change in multipolarity of near-threshold photoabsorption of nuclei. The experiment implies direct investigation of the observed effects by measuring total photoabsorption cross sections in the photon beam. The simulation is performed using the GEANT-4 code. The parameters of the facility are optimized, and the choice of the detectors for the measurements is substantiated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотон</kwd><kwd>электрон</kwd><kwd>мультипольность</kwd><kwd>пигми резонанс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photon</kwd><kwd>electron</kwd><kwd>multipolarity</kwd><kwd>pygmy resonance</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">Savran D., Aumann T., Zilges A. // Progr.
