   <abstract xml:lang="ru">
    <p>Представлены результаты расчетов коэффициентов фотоотлипания электронов от ионов О⁻ и О₂⁻ в области D ионосферы, основанные на последних измерениях сечений фотоотлипания. Расчеты выполнены для стандартной атмосферы с помощью программного кода TUV (Terrestrial UltraViolet). Получены зависимости коэффициентов фотоотлипания от высоты и зенитного угла Солнца. Нелинейный характер этих зависимостей приведет к аналогичному изменению роли процессов фотоотлипания в зависимости от высоты и солнечного зенитного угла в сравнении с другими процессами в средней атмосфере и нижней ионосфере, в особенности в сумеречных условиях. Вычисления с использованием экспериментальных спектров солнечного излучения за 2011–2020 гг., проведенные для дней зимнего и летнего солнцестояний и весеннего и осеннего равноденствий, не показали количественно значимого различия коэффициентов фотоотлипания от отрицательных ионов О⁻ и О₂⁻ в области D ионосферы.</p>

    <p>We present the results of calculation of photodetachment rates for negative ions in the D layer of the ionosphere, using recent photodetachment cross-section measurements. The calculations have been made for the standard atmosphere by means of the TUV (Terrestrial UltraViolet) code. We have obtained dependences of the photodetachment rates on altitude and solar zenith angle. The nonlinear nature of these dependences causes similar variations in the role of the photodetachement processes with altitude and solar zenith angle as compared to other processes in the middle atmosphere and the lower ionosphere, especially under terminator conditions. Calculations with solar spectrum for 2011–2020 for the summer/winter solstice and the spring/autumn equinox have shown no quantitative difference between the photodetachement rates for ions in the D layer of the ionosphere.</p>
