A kinematically complete experiment has been performed to study $\alpha$-induced deuteron breakup under the same experimental conditions as in a previous experiment. With respect to the results of the latter experiment, our correlation cross sections are about one order of magnitude larger, while they are of the same order as those at higher energies. Our analysis indicates that the experimental spectra are rather well reproduced with models involving only two-body interactions. The hypothesis of three-body forces is, therefore, not required to interpret the data.
