Abstract
This article reports on the ground-state spin and moments measured in using collinear laser spectroscopy at the CERN On-Line Isotope Mass Separator (ISOLDE) facility. From the measured hyperfine coefficients, the nuclear observables (, , , , , and have been determined. Through a comparison of the measured magnetic moments with different models, the negative moment reveals a strong component in the ground-state wave function. Consequently, a negative parity has been assigned to the ground states of . Large-scale shell-model calculations illustrate the strong sensitivity of the nuclear moments to configuration mixing and to the effective interaction employed.
