Применение весовой функции позволяет существенно уменьшать параметры регуляризации и разделять близкорасположенные спектральные линии. Проблема появления в разреженном решении ложных осцилляций решается применением итерационного алгоритма коррекции основной матрицы. Для определения параметра регуляризации, обеспечивающего максимальную разрешимость метода, используется апостериорный алгоритм минимального порогового значения. Применение алгоритма принципиально улучшает качество обработки спектров и увеличивает информативность спектроскопических методов. На примерах обработки модельных и экспериментальных мёссбауэровских спектров показана эффективность предложенного алгоритма.</p></abstract><trans-abstract xml:lang="en"><p>We proposed an algorithm for separating the overlapping spectral components using the Tikhonov weighted regularization method is proposed. The use of the weighting function allows one to significantly reduce the regularization parameters and separate closely spaced spectral lines. The problem of the appearance of spurious oscillations in a sparse solution is solved by an iterative algorithm for correcting the main matrix. To determine the regularization parameter that provides the maximum resolution of the method, the posterior minimum threshold algorithm is used. The use of the algorithm fundamentally improves the quality of spectra processing and increases the information content of the spectroscopic methods. The efficiency of the proposed algorithm is shown on examples of processing the model and experimental Moss-bauer spectra.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мёссбауэровская спектроскопия</kwd><kwd>интегральное уравнение Фредгольма 1 рода</kwd><kwd>взвешенная регуляризация</kwd><kwd>итерационный алгоритм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Mossbauer spectroscopy</kwd><kwd>Fredholm integral equation of the 1st kind</kwd><kwd>weighted regularization</kwd><kwd>iterative algorithm</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования РФ (№АААА-А17-117022250038-7)</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">D.
