Установлено, что распределения электронов не максвелловские с избытком высокоэнергичных электронов (10–20 эВ), доля которых уменьшается при удалении от катода. Особенности связываются с нелокальным механизмом формирования ФРЭЭ.</p></abstract><trans-abstract xml:lang="en"><p>Using the improved method of single Langmuir probes, the electron energy distribution functions (EEDF) were obtained in a short (10 mm) discharge gap between a rectangular hollow cathode and a mesh anode. It was found that the electron distributions are not Maxwellian with an excess of high-energy electrons (10–20 eV), the proportion of which decreases with distance from the cathode. The features are associated with the nonlocal mechanism of the EEDF formation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диагностика плазмы</kwd><kwd>метод одиночных зондов Ленгмюра</kwd><kwd>нелокальная плазма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>plasma diagnostics</kwd><kwd>single Langmuir probe method</kwd><kwd>non-local plasma</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Российский научный фонд (проект № 19-12-00310)</funding-statement><funding-statement xml:lang="en">Russian Science Foundation (project no. 19-12-00310)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">&lt;em&gt;Bernatskiy A.V., Kochetov I.V., Ochkin V.N.&lt;/em&gt; // Plasma Phys.
