Abstract
Excitations in the integrable model with two- and three-particle interactions are calculated on the basis of the Bethe ansatz equations obtained in a previous paper. It is shown that the model exhibits two kinds of excitations, one connected with the massless particle-hole excitations, the other with massive excitations corresponding to the collective motion of the pseudoparticles.Keywords
