摘要：

The spin excitations of the s = 1/2 nearly one-dimensional Heisenberg antiferromagnet, KCuF3, have been determined using neutron scattering techniques. The results at high energies show that the excitations are described by pairs of unbound spinons but, at low temperatures and energies, the scattering is described by spin wave theory.
