“…The quadrupole moments are all directly or indirectly deduced relative to that of 7 Li, including that of 6 Li which was recently remeasured very precisely by Cederberg et al [30]. The quadrupole moment of 11 Li was reported relative to that of 9 Li [24], and we reevaluate its absolute value based on the new accurate 9 Li quadrupole moment reported here.…”

The nuclear magnetic moment of 9 Li and the quadrupole moments of 8 Li and 9 Li have been measured by use of the β-asymmetry detection of nuclear magnetic resonance on optically polarized beams at ISOLDE/CERN. The radioactive beams were implanted in Si for g-factor measurements and in Zn, LiNbO 3 , and LiTaO 3 crystals for quadrupole moment measurements. The electric-field gradient V zz = 4.26(4) × 10 15 V/cm 2 is deduced for Li in Zn. Using a recently adopted reference value, Q( 7 Li) = −40.0(3) mb, we reevaluated all earlier reported nuclear quadrupole moments of 8 Li and 9 Li. Based on all available previous and present data, the adopted quadrupole moments for these isotopes are Q( 8 Li) = +31.4(2) mb and Q( 9 Li) = −30.6(2) mb. The magnetic moment of 9 Li is deduced as µ( 9 Li) = 3.43678(6)µ N . The values are compared with predictions from shell-model and cluster-model calculations.

“…7 this pair of E2 observables does not exhibit a robust correlation. Because the measured quadrupole moment of −0.08178(164) efm 2 [85] is so close to zero, the experimental data point in the correlation plot is incompatible with the rigid rotor model. The very small quadrupole moment of the ground-state is governed by more subtle structural effects rather than the robust effects from the rotor model.…”

Starting from a set of different two-and three-nucleon interactions from chiral effective field theory, we use the importance-truncated no-core shell model for ab initio calculations of excitation energies as well as electric quadrupole (E2) and magnetic dipole (M1) moments and transition strengths for selected p-shell nuclei. We explore the sensitivity of the excitation energies to the chiral interactions as a first step towards and systematic uncertainty propagation from chiral inputs to nuclear structure observables. The uncertainty band spanned by the different chiral interactions is typically in agreement with experimental excitation energies, but we also identify observables with notable discrepancies beyond the theoretical uncertainty that reveal insufficiencies in the chiral interactions. For electromagnetic observables we identify correlations among pairs of E2 or M1 observables based on the ab initio calculations for the different interactions. We find extremely robust correlations for E2 observables and illustrate how these correlations can be used to predict one observable based on an experimental datum for the second observable. In this way we circumvent convergence issues and arrive at far more accurate results than any direct ab initio calculation. A prime example for this approach is the quadrupole moment of the first 2 + state in 12 C, which is predicted with an drastically improved accuracy.

“…In this paper, we present the results of an examination of the hyperfine spectra of the molecules KBr and KI, continuing our extended investigation [1][2][3][4][5][6][7][8][9][10] of alkali halide molecules using an electric resonance molecular beam spectrometer. The experimental details as they relate to the current experiments are described in a document included in Supplementary material.…”
