Description

We show that all the features of the recent neutron scattering data by Shirane et al. on large, superconducting single crystals can be explained in a model with singlet pairing of bosonic spins. The temperature dependence of the integrated intensity seen experimentally is due to the creation of two spin excitations out of the pair condensate in one scattering event. The Goldstone modes of the theory are identified, and suggestions for experimental tests are given. (orig.)
