Ground state hyperfine structure in muonic lithium ions

Ground State Hyperfine Structure of Muonic Helium Atom

The muonic helium atom (μe2He) represents the simple three-body atomic system. The interaction between magnetic moments of the muon and electron leads to the hyperfine structure (HFS) of the energy levels. The investigation of the energy spectrum of this atom is important for the check of quantum electrodynamics for three-particle bound state. The ground state hyperfine splitting was measured m...

Ground state hyperfine splitting of high Zhydrogenlike ions

The ground state hyperfine splitting values of high Z hydrogenlike ions are calculated. The relativistic, nuclear and QED corrections are taken into account. The nuclear magnetization distribution correction (the Bohr-Weisskopf effect) is evaluated within the single particle model with the g S-factor chosen to yield the observed nuclear moment. An additional contribution caused by the nuclear s...

Hyperfine Structure of S-states in Muonic Helium Ion

Corrections of orders α5 and α6 are calculated in the hyperfine splittings of 1S and 2S energy levels in the ion of muonic helium. The electron vacuum polarization effects, the nuclear structure corrections and recoil corrections are taken into account. The obtained numerical values of the hyperfine splittings -1334.56 meV (1S state), -166.62 meV (2S state) can be considered as a reliable estim...

Hyperfine Splitting in Heavy Ions with the Nuclear Magnetization Distribution Determined from Experiments on Muonic Atoms

The hyperfine splitting in hydrogenlike 209Bi, 203Tl, and 205Tl is calculated with the nuclear magnetization determined from experimental data on the hyperfine splitting in the corresponding muonic atoms. The single-particle and configuration-mixing nuclear models are considered. The QED corrections are taken into account for both electronic and muonic atoms. The obtained results are compared w...
