- Abstract
Fundamental properties of doubly-magic nuclei, such as radius and binding energy, play a key role in theoretical calculations. Reported matter radii of 16 O have a large discrepancy, especially for results obtained from interaction cross sections. To address this issue, the published small-angle differential cross sections of proton-nuclei elastic scattering in the energy region of 200–700 MeV were reanalyzed using the Glauber model. A precise matter radius of 2.554(20) fm for 16 O was extracted. The calculated neutron skin thicknesses of 16 O by different interactions do not obviously depend on the symmetry energy, and agree with our result.
