Correlating nuclear masses and radii

Abstract : It is shown that a consistent treatment of nuclear bulk and surface effects leads to an improved version of the liquid-drop mass formula with modified symmetry and Coulomb terms. The assumptions at the basis of this bulk-surface separation are discussed. If in addition shell effects are modelled through the counting of the number of valence nucleons, a very simple mass formula is obtained with an root-meansquare deviation from the 2003 database of atomic masses of about 800 keV. Inspired by these efforts, a similar description of nuclear radii is suggested with specific reference to the difference between neutron and proton radii. Finally, the correlation between the deviations from the measured masses on the one hand and from the measured radii on the other, is studied.
