Description
The excitation energies of the Roper resonance and the stability of baryons against static quadrupole deformations are studied in the Skyrme model. Nucleon and Δ-isobar turn out to be spherical. States having a spin different from their isospin are strongly deformed and lie ≅500 MeV above the ground states. The Roper is the lowest excitation of the Skyrme soliton located at ≅300 MeV excitation energy
