    "abstract": "The hyperfine structure (hfs) of electron levels of $^{238}_{92}$U ions with\nthe nucleus excited in the low-lying rotational $2^+$ state with an energy\n$E_{2^+} = 44.91$ keV is investigated. In hydrogenlike uranium, the hfs\nsplitting for the $1s_{1/2}$-ground state of the electron constitutes 1.8 eV.\nThe hyperfine-quenched (hfq) lifetime of the $1s2p ^3P_0$ state has been\ncalculated for heliumlike $^{238}_{92}$U and was found to be two orders of\nmagnitude smaller than for the ion with the nucleus in the ground state. The\npossibility of a precise determination of the nuclear $g_r$ factor for the\nrotational $2^+$ state by measurements of the hfq lifetime is discussed.",
