Abstract: High-precision mass and charge radius measurements on Ne17-22, including the proton-halo candidate Ne-17, have been performed with Penning trap mass spectrometry and collinear laser spectroscopy. The Ne-17 mass uncertainty is improved by factor 50, and the charge radii of Ne17-19 are determined for the first time. The fermionic molecular dynamics model explains the pronounced changes in the ground-state structure. It attributes the large charge radius of Ne-17 to an extended proton configuration with an s(2) component of about 40%. In Ne-18 the smaller radius is due to a significantly smaller s(2) component. The radii increase again for Ne19-22 due to cluster admixtures.
