Changes in mean square (ms) nuclear charge radii of Ar isotopes across the 1f(7/2) shell are studied by fast-beam collinear laser spectroscopy using an ultra-sensitive detection method based on optical pumping and state-selective collisional ionization. The new data set on Ar, in combination with the known charge radii of K, Ca, and Ti in the nu 1f(7/2) shell, offers an opportunity to obtain a more complete overview of nuclear radii trends around the proton shell closure Z=20 and between the neutron shell closures N=20 and N=28.status: publishe
