Abstract
A recently developed dipolar-exchange theory of quantized spin-wave (SW) modes in cylindrical ferromagnetic nanowires is used here for the calculation of the inelastic neutron cross section in different ordered lattices of such wires. The Hamiltonian formalism for bulk spin-wave excitations in nanowires is developed under the following simplifications: (1) wires in the array do not interact with each other; (2) an applied magnetic field is equal to zero. The calculated cross section is analyzed as a function of different shapes of SW modes, SW frequencies, quantized radial wave vector components, and the momentum transfer along the wire.
