We propose an algebraic description of the geometric structure of baryons in terms of the algebra U(7). We construct a mass operator that preserves the threefold permutational symmetry and discuss a collective model of baryons with the geometry of an oblate top. PACS numbers: 14.20-c, 14.20.Dh, 14.20.Gk, 03.65.Fd

We reanalyze the world data on the electromagnetic form factors of the nucleon. The calculations are performed in the framework of an algebraic model of the nucleon combined with vector meson dominance.

Masses, deformations, radii, and single-particle properties of the very neutron-rich Sulfur isotopes are investigated in the framework of the self-consistent mean-field theory. The stability of the N=28 magic gap around 44 S is discussed.
