Процедура и методы. С помощью специального разложения волновой функции двумерное уравнение Шредингера сведено к решению краевой задачи Штурма-Лиувилля для системы дифференциальных уравнений. Для решения задачи поиска собственных значений матрицы, получаемой при конечно-разностной аппроксимации производных, применён метод обратных итераций со сдвигом. Результаты. Определены значения уровней энергии и соответствующие им собственные волновые функции квантовой частицы в поле двумерного диполя. Теоретическая и/или практическая значимость. С помощью предложенного численного алгоритма с хорошей точностью получены значения энергетических уровней связанных состояний квантовой частицы в поле двумерного диполя. Получено согласие с результатами других авторов, использовавших вариационный подход, для которого отсутствуют оценки ошибок вычисленных значений относительно истинного решения. Выполненные нами расчёты с известной оценкой точности восполняют этот пробел.</p></abstract><trans-abstract xml:lang="en"><p>Aim of the paper is a numerical investigation of energy levels of a quantum particle in a field of a two-dimensional dipole, based on the numerical algorithm proposed for solving the full two-dimensional Schrцdinger equation. Methodology. With the help of special expansion of a wave function the two-dimensional Schrцdinger equation was transformed to the Sturm-Liouville boundary problem for the system of differential equations. The method of inverted iterations with a shift was applied to the matrix eigenvalues search problem, that was obtained after a finite-difference approximation of the derivatives. Results. The low-lying energy levels and the corresponding wave functions of a quantum particle in a field of a two-dimensional dipole were determined. Research implications. The energy levels of bound states of a quantum particle in a field of a two-dimensional dipole were obtained using the proposed numerical algorithm. The agreement was obtained with the work of other author, where the variational approach was used, for which there is no error estimates of the calculated values relative to the exact solution. The calculations that were carried out by us with known convergence and error estimates fill this gap.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>двумерное уравнение Шредингера</kwd><kwd>анизотропные взаимодействия</kwd><kwd>численный алгоритм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>two-dimensional Schrödinger equation</kwd><kwd>anisotropic interactions</kwd><kwd>numerical algorithm</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">Martiyanov K., Makhalov V., Turlapov A.
