New measurements of the interaction cross sections of {sup 22,23}O at 900A MeV performed at the GSI, Darmstadt are reported that address the unsolved puzzle of the large cross section previously observed for {sup 23}O. The matter radii for these oxygen isotopes extracted through a Glauber model analysis are in good agreement with the new predictions of the ab initio coupled-cluster theory reported here. They are consistent with a {sup 22}O + neutron description of {sup 23}O as well.
