Measurement of hyperfine structure and the Zemach radius in using optical Ramsey technique
Wei Sun, Pei-Pei Zhang, Peng-peng Zhou +10
We investigate the -- () transitions in using the optical Ramsey technique and achieve the most precise values of the hyperfine spl…
Precision calculation of hyperfine structure of Be ions
Xiao-Qiu Qi, Pei-Pei Zhang, Zong-Chao Yan +4
The hyperfine structures of the and states of the Be and Be ions are investigated within the framework of the nonrelativistic quantu…
Measurement of a helium tune-out frequency: an independent test of quantum electrodynamics
B. M. Henson, J. A. Ross, K. F. Thomas +9
Despite quantum electrodynamics (QED) being one of the most stringently tested theories underpinning modern physics, recent precision atomic spectroscopy measurements have uncovere…
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…
Origin of the Low Energy Structure in Above Threshold Ionization
Atef S. Titi, Gordon W. F. Drake
We present an ab initio analytic theory to account for both the very low energy structure (VLES) [C. Y. Wu et al., Phys. Rev. Lett. 109, 043001 (2012); W. Quan et al., Phys. Rev. L…
The 2S-2P Lamb Shift in He+
U. D. Jentschura, G. W. F. Drake
The current theoretical status of the Lamb shift in He+ is discussed. Recent calculations of two-loop binding corrections to the Lamb shift significantly shift the theoretical valu…
