The hyperfine structures of the and states of the Be and Be ions are investigated within the framework of the nonrelativistic quantu…
Higher-order corrections to spin-spin scalar interactions in HD and H
Jean-Philippe Karr, Mohammad Haidar, Laurent Hilico +2
The largest hyperfine interaction coefficients in the hydrogen molecular ion HD, i.e. the electron-proton and electron-deuteron spin-spin scalar interactions, are calculated wi…
Precision calculation of hyperfine structure and the Zemach radii of Li ions
Xiao-Qiu Qi, Pei-Pei Zhang, Zong-Chao Yan +7
The hyperfine structures of the states of the Li and Li ions are investigated theoretically to extract the Zemach radii of the Li and Li nuclei…
Complex coordinate rotation method based on gradient optimization
Zhi-Da Bai, Zhen-Xiang Zhong, Zong-Chao Yan +1
In atomic, molecular, and nuclear physics, the method of complex coordinate rotation is a widely used theoretical tool for studying resonant states. Here, we propose a novel implem…
Hyperfine structure in the H and HD molecular ions at order
Vladimir Korobov, Jean-Philippe Karr, Mohammad Haidar +1
A complete effective Hamiltonian for relativistic corrections at orders and in a one-electron molecular system is derived from the NRQED Lagrangian. It includes…
