Данный полуэмпирический метод широко используется в атомной физике для предсказания энергий возбужденных состояний без необходимости расчета сечений фотоионизации. Полученные результаты сравниваются с существующей базой данных NIST, содержащей данные измерений Крамидала и Advanced Light Source. Анализ полученных результатов осуществляется в рамках стандартной теории квантовых дефектов процедуры SCUNC. Результаты демонстрируют эффективность формализма SCUNC при анализе измерений.</p></abstract><trans-abstract xml:lang="en"><p>   We report calculations of accurate high-lying resonance energies of the triplet and the singlet states of the Strontium Rydberg series. Calculations are performed using the Screening Constant by Unit Nuclear Charge (SCUNC) method from n = 12 to 60. This semi-empirical method is widely used in atomic physics to predict energies of excited states without requiring calculation of photoionization cross-sections. Present results are compared with the existing NIST database of Kramidal and Advanced Light Source measurements of Couturier et al. Analysis of the present results is achieved in the framework of the standard quantum-defect theory of the SCUNC procedure. In addition, the present work demonstrates the strength of the SCUNC formalism to assist experimenters in the analysis of measurements.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотоионизация</kwd><kwd>энергия резонанса</kwd><kwd>квантовый дефект</kwd><kwd>ридберговская серия</kwd><kwd>метод констант экранирования на единицу заряда ядра</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photoionization</kwd><kwd>resonance energy</kwd><kwd>quantum defects</kwd><kwd>Rydberg series</kwd><kwd>SCUNC</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Это исследование не получило внешнего финансирования</funding-statement><funding-statement xml:lang="en">This research received no external funding</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">J.
