AbstractUpper and lower bounds to the nucleon electric polarizability are discussed, within the constituent quark model, by using a sum rule approach for the nucleon response to an external static electric field. We find that the SU(6) breaking terms of the quark-quark potential are important in order to evaluate the size and the electric response of the nucleon consistently and we discuss the role of the hyperfine interaction in some detail.
