Autor: S. Schmidt, J. Billowes, M.L. Bissell, K. Blaum, R.F. Garcia Ruiz, H. Heylen, S. Malbrunot-Ettenauer, G. Neyens, W. Nörtershäuser, G. Plunien, S. Sailer, V.M. Shabaev, L.V. Skripnikov, I.I. Tupitsyn, A.V. Volotka, X.F. Yang
Publikováno v: Physics Letters B, Vol 779, Iss , Pp 324-330 (2018)
The hyperfine structure splitting in the 6p3S3/24→6p27sP1/24 transition at 307 nm in atomic 208Bi was measured with collinear laser spectroscopy at ISOLDE, CERN. The hyperfine A and B factors of both states were determined with an order of magnitud

Model-QED-operator approach to relativistic calculations of the nuclear recoil effect in many-electron atoms and ions
Autor: I. S. Anisimova, A. V. Malyshev, D. A. Glazov, M. Y. Kaygorodov, Y. S. Kozhedub, G. Plunien, V. M. Shabaev
A model-operator approach to fully relativistic calculations of the nuclear recoil effect on energy levels in many-electron atomic systems is worked out. The one-electron part of the model operator for treating the normal mass shift beyond the Breit

Stimulated vacuum emission and photon absorption in strong electromagnetic fields
Autor: I. A. Aleksandrov, A. Di Piazza, G. Plunien, V. M. Shabaev
Publikováno v: Physical Review D
Physical Review
According to quantum electrodynamics (QED), a strong external field can make the vacuum state decay producing electron-positron pairs. Here we investigate emission of soft photons which accompanies a nonperturbative process of pair production. Our an

Total yield of electron-positron pairs produced from vacuum in strong electromagnetic fields: Validity of the locally constant field approximation
Autor: D. G. Sevostyanov, G. Plunien, V. M. Shabaev, I. A. Aleksandrov
Publikováno v: Physical Review
The widely used locally constant field approximation (LCFA) can be utilized in order to derive a simple closed-form expression for the total number of particles produced in the presence of a strong electromagnetic field of a general spatiotemporal co

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: V M, Shabaev, D A, Glazov, A M, Ryzhkov, C, Brandau, G, Plunien, W, Quint, A M, Volchkova, D V, Zinenko
Publikováno v: Physical review letters. 128(4)
A method is proposed to determine the M1 nuclear transition amplitude and hence the lifetime of the "nuclear clock transition" between the low-lying (∼8 eV) first isomeric state and the ground state of ^{229}Th from a measurement of the ground-stat

Ground‐state energy of uranium diatomic quasimolecules with one and two electrons
Autor: Dmitry A. Glazov, G. Plunien, Artem A. Kotov, Anastasia V. Vladimirova, V. M. Shabaev, A. V. Malyshev
Publikováno v: X-Ray Spectrometry. 49:110-114
Ground-state energies of the one- and two-electron uranium dimers are calculated for internuclear distances in the range D=40--1000 fm and compared with the previous calculations. The generalization of the dual-kinetic-balance approach for axially sy

One-electron energy spectra of heavy highly charged quasimolecules
Autor: G. Plunien, V. M. Shabaev, Artem A. Kotov, Dmitry A. Glazov
The generalized dual-kinetic-balance approach for axially symmetric systems is employed to solve the two-center Dirac problem. The spectra of one-electron homonuclear quasimolecules are calculated and compared with the previous calculations. The anal

Autor: P. H. Mokler, Horst Schmidt-Böcking, Y. S. Kozhedub, Michael Schulz, Reinhold Schuch, I. I. Tupitsyn, V. M. Shabaev, G. Plunien
Publikováno v: Physical Review A. 101
We have measured characteristic K x rays in coincidence with the scattered particles from collisions of hydrogenlike Ge ions with Kr atoms. The ions were first accelerated to 8.6 MeV/amu, post-stri ...
