Abstract
Collinear laser spectroscopy on 58–75Cu isotopes was performed at the CERN-ISOLDE radioactive ion beam
facility. In this paper we report on the isotope shifts obtained from these measurements. State-of-the-art atomic
physics calculations have been undertaken in order to determine the changes inmean-square charge radii δr2A,A
from the observed isotope shifts. A local minimum is observed in these radii differences at N = 40, providing
evidence for a weak N = 40 sub-shell effect. However, comparison of δr2A,A
with a droplet model prediction
including static deformation deduced from the spectroscopic quadrupole moments, points to the persistence of
correlations at N = 40.
