The parameters of the embedded potential were found taking into account the temperature dependence of the density, energy and compressibility of liquid gold. At 1973 K the diffraction data are not accurate enough for further calculations. It is shown that the EAM potential calculated at 1423 K allows us to build sufficiently adequate models of gold at temperatures up to 3000 K. The calculated self-diffusion coefficients are 25–30% lower than those obtained on the basis of the effective medium theory, but in general the computer calculations of atomic mobility agree quite well.</p></abstract><trans-abstract xml:lang="ru"><p>С использованием парных корреляционных функций жидкого золота Васеды рассчитаны по алгоритму Шоммерса парные вклады в потенциалы ЕАМ при температурах 1423, 1573, 1773 и 1973 К. Параметры потенциала погружения найдены с учетом температурной зависимости плотности, энергии и сжимаемости жидкого золота. При 1973 К дифракционные данные недостаточно точны для дальнейших расчетов. Показано, что потенциал ЕАМ, рассчитанный при 1423 К, позволяет строить достаточно адекватные модели золота при температурах до 3000 К. Расчетные коэффициенты самодиффузии на 25–30% ниже полученных на основе теории эффективной среды, но в целом компьютерные расчеты подвижности атомов неплохо согласуются.</p></trans-abstract><kwd-group xml:lang="en"><kwd>gold</kwd><kwd>liquid metal</kwd><kwd>embedded atom model (EAM)</kwd><kwd>pair potential</kwd><kwd>Schommers algorithm</kwd><kwd>pair correlation function</kwd><kwd>self-diffusion</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>золото</kwd><kwd>жидкий металл</kwd><kwd>модель погруженного атома (EAM)</kwd><kwd>парный потенциал</kwd><kwd>алгоритм Шоммерса</kwd><kwd>парная корреляционная функция</kwd><kwd>самодиффузия</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Schommers W. // Phys.
