We calculate the relative intensities of the main incommensurate and third harmonic peaks expected from elastic neutron scattering for various stripe phases observed in nickelates and some cuprate superconductors. We consider vertical and diagonal stripes and compare both site- and bond-centered configurations of the domain walls. Upon comparing the calculated ratio of the main incommensurate peaks to the next harmonic peaks in these configurations to the background and errors in neutron scattering experiments, we conclude that in most cases in the cuprates, the harmonic peaks expected from stripes are too weak to be detected.
