Nuclear moments of germanium isotopes near N = 40

NUCLEAR MOMENTS ^69,71,73Ge; measured hyperfine structure spectra using collinear laser spectroscopy setup COLLAPS at ISOLDE-CERN; deduced magnetic electric hyperfine structure constants, magnetic dipole moment μ, and electric quadrupole moment Q, with the hyperfine fields for the atomic levels calculated using state-of-the-art atomic relativistic Fock-space coupled-cluster method. Comparison with previous experimental results, and with large-scale shell-model calculations using JUN45 interaction, suggesting mixed wave-function configurations. Systematics of low-energy levels, g factors and quadrupole moments of ^67,69,71,73Zn, ^69,71,73,75Ge, ⁷³Se. ^69,71,73Ge isotopes produced in Zr(p, X), E=1.4 GeV reaction, followed by acceleration of germanium ions to 50 keV, and mass separation using the high-resolution isotope separator (HRS), and finally bunched in a gas-filled linear Paul trap (ISCOOL).
