Recent experiments on the quasi-one-dimensional antiferromagnet copper benzoate revealed a magnetic-field-induced gap coexisting with (ferro)magnetic order. A theory explaining these findings has been proposed by Oshikawa and Affleck. In the present work we discuss consequences of this theory for inelastic neutron-scattering experiments by calculating the dynamical magnetic susceptibilities close to the antiferromagnetic wave vector by the form-factor method.
