Collinear laser spectroscopy was performed on the 63,64,66,68−82Ga 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 63,70Ga, measured on an atomic transition in the neutral atom. The ground-state spin of 63Ga 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.
