Взаимодействие проявляется в том, что поле излучения от каждой частицы определяется не только внешним полем электрона, но и полем соседней частицы. Исходя из полученных выражений для поля излучения, определена функция поляризуемости кластера, которая характеризует его отклик на поле электрона как целого. Интересно, что полученная функция отклика кластера на внешнее поле даже в рамках линейной теории в общем случае зависит от самого внешнего поля.</p></abstract><trans-abstract xml:lang="en"><p>The study considers diffraction radiation, which is excited when an electron moves near a cluster of two interacting subwavelength particles. The interaction is manifested in the fact that the radiation field from each particle is determined not only by the external field of the electron, but also by the field of the neighboring particle. Based on the obtained expressions for the radiation field, the function of cluster polarizability is determined. It characterizes the cluster response to the field of the electron as a whole. It is interesting that the obtained response function of the cluster to an external field, even in the framework of linear theory, generally depends on the external field itself.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поляризуемость</kwd><kwd>поляризационное излучение</kwd><kwd>взаимодействие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polarizability</kwd><kwd>polarization radiation</kwd><kwd>interaction</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">Smith S.J., Purcell E.M. // Phys.
