Граничное расстояние r0 определяется параметрами этих потенциалов. Точное непрерывное решение радиального уравнения Шрёдингера выражено через вырожденные гипергеометрические функции. Получены дискретные уровни энергии. Представлены графические иллюстрации для спектра энергии и радиальных волновых функций.</p></abstract><trans-abstract xml:lang="en"><p>The spherically symmetric potential is considered, whose dependence on the distance r is described by the smooth composition of Coulomb at r &lt; r0 and oscillator at r &gt; r0 potentials. The boundary distance r0 is determined by the parameters of these potentials. The exact continuous solution of the radial Schrodinger equation is expressed in terms of the confluent hypergeometric functions. The discrete energy levels are obtained. The graphic illustrations for the energy spectrum and the radial wave functions are presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>композиция кулоновского и осцилляторного потенциалов</kwd><kwd>радиальные волновые функции</kwd><kwd>уровни энергии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composition of Coulomb and oscillator potentials</kwd><kwd>radial wave functions</kwd><kwd>energy levels</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">Давыдов, А.
