Показано, что в продольном магнитном поле резонанс N-типа расщепляется на три эквидистантные компоненты. Проведено сравнение параметров резонанса N-типа, формируемых в парах атомов цезия и рубидия. Установлено, что при формировании резонанса N-типа начальным и конечным уровнями являются нижние основные уровни Fg = 1, 2.</p></abstract><trans-abstract xml:lang="en"><p>An N-type optical resonance formed in the Ʌ-system of potassium atoms (D1 lines) using two CW narrow-band lasers, a spectroscopic cell with a length of 1.5 cm which contains vapors of potassium atoms, and a buffer neon gas with a partial pressure of 20 Torr has been investigated. It is shown that the N-type resonance splits into three equidistant components in a longitudinal magnetic field. A comparison of the N-type resonance parameters formed in the vapors of cesium and rubidium atoms has been presented. It is found that when the N-type resonance is formed, the initial and final levels are the lower ground levels Fg = 1, 2.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптический резонанс N-типа</kwd><kwd>пары атомов калия</kwd><kwd>цезия и рубидия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>N-type optical resonance</kwd><kwd>vapor of potassium</kwd><kwd>cesium</kwd><kwd>and rubidium atoms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор благодарен Д.
