Neutron-scattering spectra are computed for noncubic cerium Kondo compounds within the effective resonant-scattering Hamiltonian which describes both Kondo and crystal-field effects, thus extending to noncubic compounds a previous calculation [Phys. Rev. B 33, 1804 (1986)]. Both the longitudinal and transverse susceptibilities are taken into account, and the results depend on the nature of the ground state considered. The model is finally applied to the experimental neutron-scattering spectra of ${\mathrm{CeAl}}_{3}$ and ${\mathrm{CeCu}}_{2}$${\mathrm{Si}}_{2}$ compounds.
