На основе данных о скоростях радиационного распада вычислены радиационные времена жизни некоторых уровней, которые хорошо согласуются с другими доступными теоретическими и экспериментальными результатами. Предсказаны новые данные для нескольких уровней, для которых отсутствуют какие-либо теоретические и/или экспериментальные результаты, что обусловливает необходимость точных измерений.</p></abstract><trans-abstract xml:lang="en"><p>Herein the energies of low-lying levels, wavelengths, transition rates, and line strengths for electric dipole allowed (E1) and forbidden (M1) lines in Ne- to Al-like ions of tantalum have been calculated using the GRASP2Kpackage, which is based on the multiconfiguration Dirac-Hartree-Fock (MCDHF) method. From our radiative decay rates, we also calculated the radiative lifetimes of some levels. The present results are in good agreement with other available theoretical and experimental values. We predict new data for several levels where no other theoretical and/or experimental results are available, stipulating the necessity of precise measurements.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>низколежащие уровни</kwd><kwd>длина волны</kwd><kwd>скорость перехода</kwd><kwd>интенсивность линии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>low-lying levels</kwd><kwd>wavelength</kwd><kwd>transition rate</kwd><kwd>line strength</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported in part by the Science and Technology Research Project of Education Department of the Jiangxi Province of China (Grant GJJ181488), the National Natural Science Foundation of China (Grants 11565020, 11965010), and the Natural Science Foundation Hainan province (Grants 118MS071, 2019RC239).</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">I.
