The fine and hyperfine structures of pionic helium metastable states is calculated within the formalism of the Breit–Pauli Hamiltonian by using the variationally generated wave functions in Hylleraas coordinates. Our results not only verify the exi

The transition frequency of (n,ℓ)=(17,16)→(16,15) in pionic helium-4 is calculated to an accuracy of 4 ppb (parts per billion), including relativistic and quantum electrodynamic corrections up to O(R_{∞}α^{5}). Our calculations significantly i

The largest hyperfine interaction coefficients in the hydrogen molecular ion ${\mathrm{HD}}^{+}$, i.e., the electron-proton and electron-deuteron spin-spin scalar interactions, are calculated with estimated uncertainties slightly below 1 ppm. The ${(

The hyperfine structures of the $2{^{3}S}_{1}$ states of the $^{6}{\mathrm{Li}}^{+}$ and $^{7}{\mathrm{Li}}^{+}$ ions are investigated theoretically to extract the Zemach radii of the $^{6}\mathrm{Li}$ and $^{7}\mathrm{Li}$ nuclei by comparing with p

Precision spectroscopy of ${\mathrm{Li}}^{+}$ is a promising testing ground for bound-state quantum electrodynamics (QED) and for measurements of nuclear properties such as the Zemach radius. We investigate the hyperfine and fine-structure splittings

A complete effective Hamiltonian for relativistic corrections at orders $m{\ensuremath{\alpha}}^{6}$ and $m{\ensuremath{\alpha}}^{6}(m/M)$ in a one-electron molecular system is derived from the nonrelativistic QED Lagrangian. It includes spin-indepen

The hyperfine structures of the 2^{3}S_{1} states of the ^{6}Li^{+} and ^{7}Li^{+} ions are investigated theoretically to extract the Zemach radii of the ^{6}Li and ^{7}Li nuclei by comparing with precision measurements. The obtained Zemach radii are

The nonrelativistic QED (NRQED) approach is applied to the calculation of relativistic corrections to the fine and hyperfine structure of hydrogenlike atoms at orders $m{\ensuremath{\alpha}}^{6}$ and $m{\ensuremath{\alpha}}^{6}(m/M)$. Results are fou
