Inelastic neutron scattering experiments have been carried out on a YBa2(Cuo.98Zno.02)306.39 single crystal to investigate the spin-excitation spectrum in the hole-doped antiferromagnetic state. New excitations are found at low energy as a consequence of electron hole interactions, whereas standard
