Autor: Zinenko, D. V., Glazov, D. A., Kosheleva, V. P., Volotka, A. V., Fritzsche, S.

Publikováno v: Phys. Rev. A 107, 032815 (2023)

We present the systematic QED treatment of the electron correlation effects on the $g$ factor of lithiumlike ions for the wide range of nuclear charge number $Z= 14$ -- $82$. The one- and two-photon exchange corrections are evaluated rigorously withi

g Factor of Lithiumlike Silicon and Calcium: Resolving the Disagreement between Theory and Experiment

Autor: Kosheleva, V. P., Volotka, A. V., Glazov, D. A., Zinenko, D. V., Fritzsche, S.

The bound-electron g factor is a stringent tool for tests of the Standard Model and the search for new physics. The comparison between an experiment on the g factor of lithiumlike silicon and the two recent theoretical values revealed the discrepanci

Ground-state $g$ factor of highly charged $^{229}$Th ions: an access to the M1 transition probability between the isomeric and ground nuclear states

Autor: Shabaev, V. M., Glazov, D. A., Ryzhkov, A. M., Brandau, C., Plunien, G., Quint, W., Volchkova, A. M., Zinenko, D. V.

Publikováno v: Phys. Rev. Lett. 128, 043001 (2022)

A method is proposed to determine the $M1$ nuclear transition amplitude and hence the lifetime of the "nuclear clock transition" between the low-lying ($\sim 8$ eV) first isomeric state and the ground state of $^{229}$Th from a measurement of the gro

$g$-factor of Boronlike Argon $^{40}\textrm{Ar}^{13+}$

Autor: Arapoglou, I., Egl, A., Höcker, M., Sailer, T., Tu, B., Weigel, A., Wolf, R., Cakir, H., Yerokhin, V. A., Oreshkina, N. S., Agababaev, V. A., Volotka, A. V., Zinenko, D. V., Glazov, D. A., Harman, Z., Keitel, C. H., Sturm, S., Blaum, K.

We have measured the ground-state $g$-factor of boronlike argon $^{40}\textrm{Ar}^{13+}$ with a fractional uncertainty of \SI{1.4e-9}{} with a single ion in the newly developed ALPHATRAP double Penning-trap setup. The here obtained value of $g=0.663\

Ground-state $g$ factor of middle-$Z$ boronlike ions

Autor: Agababaev, V. A., Glazov, D. A., Volotka, A. V., Zinenko, D. V., Shabaev, V. M., Plunien, G.

Publikováno v: J. Phys.: Conf. Ser. 1138, 012003 (2018)

Theoretical calculations of the interelectronic-interaction and QED corrections to the $g$ factor of the ground state of boronlike ions are presented. The first-order interelectronic-interaction and the self-energy corrections are evaluated within th

$g$ factor of the $[(1s)^2(2s)^2 2p]~{}^2P_{3/2}$ state of middle-$Z$ boronlike ions

Autor: Agababaev, V. A., Glazov, D. A., Volotka, A. V., Zinenko, D. V., Shabaev, V. M., Plunien, G.

Theoretical \emph{g}-factor calculations for the first excited \exst state of boronlike ions in the range $Z$=10--20 are presented and compared to the previously published values. The first-order interelectronic-interaction contribution is evaluated
