In this approach, a multidimensional Schr¨odinger equation is reduced to a system of the coupled second-order ordinary differential equations on a finite interval with the homogeneous boundary conditions of the third type at the leftand right-boundary points for continuous spectrum problem, or a set of first, second and third type boundary conditions for discrete spectrum problem. The resulting system of these equations containing the potential matrix elements and first-derivative coupling terms is solved using high-order accuracy approximations of the finite element method.</abstract><trans-abstract xml:lang="ru">Представлено краткое описание программ на языке Фортран 77 для вычисления энергетических уровней, матриц амплитуд отражения и прохождения и соответствующих волновых функций в адиабатическом подходе со связанными каналами. В этом подходе многомерное уравнение Шрёдингера сводится к системе связанных обыкновенных дифференциальных уравнений второго порядка на конечном интервале с однородными граничными условиями третьего рода на левой и правой граничных точках для задачи непрерывного спектра или набора граничных условий первого, второго и третьего рода для задачи дискретного спектра. Полученная система уравнений, содержащая матричные потенциалы, а также связанная слагаемыми, содержащими первые производные, решается в приближении высокого порядка точности методом конечных элементов.</trans-abstract><kwd-group xml:lang="en"><kwd>boundary value problem</kwd><kwd>multichannel scattering problem</kwd><kwd>finite element method</kwd><kwd>Kantorovich method</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>краевая задача</kwd><kwd>многоканальная задача рассеяния</kwd><kwd>метод конечных элементов</kwd><kwd>метод Канторовича</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>A Program Package for Solution of Two-Dimensional Discrete and Continuum Spectra Boundary-Value Problems in Kantorovich (Adiabatic) Approach / O.
