Abstract
Inelastic neutron scattering experiments have been carried out on a YB a2(Cu0.98Zn0.02)(3)O-6.39 Single crystal to investigate the spin-excit ation spectrum in the hole-doped antiferromagnetic state. New excitati ons are found at low energy as a consequence of electron-hole interact ions, whereas standard magnons are recovered at sufficiently high ener gy.
