Semi-empirical determination of the nuclear quadrupole moment of $$^{109}$$ 109 Sn

摘要: The nuclear quadrupole moment (Q) of $$^{109}$$ Sn was determined by means hyperfine structure (hfs) many-body parametrization method. splittings for isotopes $$^{117-131}$$ recently measured Yordanov et al. (Commun Phys 3:1, 2020) were used in multiconfiguration semi-empirical calculations. contributions from the second-order perturbation theory to magnetic dipole structure, concerning electrostatically correlated interactions, taken into consideration even and odd configurations simultaneously. Contributions electric spin–orbit included first time.
