Nuclear mean-square charge radii of Ga-63,Ga-64,Ga-66,Ga-68-82 nuclei: No anomalous behavior at N=32

Abstract : Collinear laser spectroscopy was performed on the Ga-63,Ga-64,Ga-66,Ga-68-82 isotopes with neutron numbers from N = 32 to N = 51. These measurements were carried out at the ISOLDE radioactive ion beam facility at CERN. Here we present the nuclear mean-square charge radii extracted from the isotope shifts and, for the lighter isotopes, new spin and moment values. New ground-state nuclear spin and moments were extracted from the hyperfine spectra of Ga-63,Ga-70, measured on an atomic transition in the neutral atom. The ground-state spin of Ga-63 is determined to be I = 3/2. Analysis of the trend in the change in mean-square charge radii of the gallium isotopes demonstrates that there is no evidence of anomalous charge radii behavior in gallium in the region of N = 32.
