摘要：

The dynamical structure factor of the frustrated spin-1/2 Heisenberg model for a series of frustration parameters at finite temperatures is presented. A sharp upper boundary of the spinon continuum is found. A simple method to extract the nearest-neighbor coupling J from the spectral width is suggested. Signatures of frustration are discussed and a comparison with neutron inelastic-scattering data is given.
