Inelastic neutron scattering has been used to obtain a comprehensive description of the absolute dynamical spin susceptibility χ'' (q,ω) of the underdoped superconducting cuprate YBa₂ Cu₃ O₆.₅ (Tc = 52 K) over a wide range of energies and temperatures (2 meV ≤ ℏ ω≤ 120 meV and 5K ≤ T ≤ 200K). Spin excitations of two different symmetries (even and odd under exchange of two adjacent CuO₂ layers) are observed which, surprisingly, are characterized by different temperature dependences. The excitations show dispersive behavior at high energies.
