      <abstract xml:lang="ru">
        <p>Как известно, пары щелочных металлов ионизируются на чистой поверхности чужеродного металла, если работа выхода последнего больше энергии ионизации щелочного атома. Это явление объясняется наступлением термодинамического равно­весия в системе поверхность металла—атом при соударениях ...</p>

      <abstract xml:lang="en">
        <p>As is known, alkali metal vapors ionize on the clean surface of a foreign metal if the output of the latter is greater than the ionization energy of the alkali atom. This phenomenon is explained by the occurrence of thermodynamic equilibrium in the metal-atom surface system during collisions...</p>
