Abstract
A scaling approach to two-magnon excitations in general S quantum spin chains is presented. The local densities of two-magnon excitations can be obtained directly without solving the one-magnon problem beforehand. Special features of the excitation spectrum are related to the complete integrability of the model.Keywords
