Investigating Role of Electron Correlation Effects via Triple Excitations for Precise Evaluation of Energies and Hyperfine Structure Constants in Na
Vaibhav Katyal, B. K. Sahoo
Accurate determination of hyperfine structure constants in atomic systems provides important insight into the interplay of electron correlation and relativistic effects in the nucl…
Nuclear Charge Radii of Sr Isotopes: Reevaluation based on Transition Frequency Measurements in the manifold in Sr
J. Palmes, K. König, K. König +13
High-precision quasi-simultaneous collinear and anticollinear laser spectroscopy was performed on the (D1), $5s\,^2S_{1/2}\rightarrow 5p\,^…
Analytical Representation for the Electronic Contribution of the Nuclear Schiff Interaction Hamiltonian
Satoshi Toda, Yasuto Masuda, Naohiro Tomiyama +4
The nuclear Schiff interaction (NSI) arises from a nuclear force that simultaneously violates spatial parity (P) and time reversal (T) symmetries, where T symmetry is equivalent to…
Ag I model atom and the 3D non-LTE solar silver abundance
Sema Caliskan, Anish M. Amarsi, Per Jönsson +2
Silver is an important light neutron-capture element whose stellar abundances help constrain the origin of the weak r-process. The Sun is an important reference point for such stud…
