Calculation of the hyperfine structure of Dy, Ho, Cf, and Es

ATOMIC PHYSICS Dy, Ho, Cf, Es; calculated the magnetic dipole HFS constants A and electric quadrupole HFS constant B for the sake of interpretation of the measurements in terms of nuclear magnetic moment μ and electric quadrupole moment Q using the configuration interaction (CI) method for open shells with a large number of valence electrons.

Using isotope shift for testing nuclear theory: The case of nobelium isotopes

NUCLEAR STRUCTURE ^252,254No; calculated nuclear charge distributions, rms charge radii for five nuclear models using covariant density functional theory (CDFT) with state-of-the-art covariant energy density functionals, isotope shifts and field isotope shifts for four electric dipole atomic transitions using CI+MBPT method. Comparison with experimental data. ²⁵⁴No, ²⁸⁶No; calculated difference in charge radii, isotope shifts between ²⁵⁴No and hypothetical ²⁸⁶No in different nuclear models for four electric dipole transitions from the ground state.
