Abstract

As suggested by the bag model, we assume that the ground states of the nucleon and the

Δ

are nearly spherical, but the excited even-parity states are quite deformed. This deformation is responsible for the observed low-lying excitations

N (1440) {\frac{1}{2}}^{+}

and

Δ (1600) {\frac{3}{2}}^{+}

, on which rotational bands are built.
