Zemach radii and nuclear structure effects in hyperfine splitting of Lithium
Yilong Yang, Evgeny Epelbaum, Chen Ji +1
Nuclear structure effects are essential for describing hyperfine splittings from high-precision atomic spectroscopy measurements. These effects are often parametrized by the effect…
Improved nuclear-structure corrections to the hyperfine splitting of electronic and muonic deuterium
Jose Bonilla, Thomas R. Richardson, Sonia Bacca +2
We calculate the nuclear-structure correction to the hyperfine splitting in both electronic and muonic deuterium using interactions from chiral effective field theory. We explore t…
The Be photodisintegration cross section within Cluster Effective Field Theory
Ylenia Capitani, Elena Filandri, Chen Ji +2
A low-energy calculation of Be photodisintegration cross section is presented within an cluster approach. The and contact interactions are derived from cluste…
Nuclear Structure Effects on Hyperfine Splittings in Ordinary and Muonic Deuterium
Chen Ji, Xiang Zhang, Lucas Platter
Precision spectroscopy of hyperfine splitting (HFS) is a crucial tool for investigating the structure of nuclei and testing quantum electrodynamics (QED). However, accurate theoret…
