We present cumulative fission product yields from the U238(n,f) reaction at an incident energy of 4.6 MeV for fission products with half-lives from less than one second to several hours. We employed direct γ-ray spectroscopy to measure unseparated fission products with a conventional neutron activation analysis and a cyclic activation technique using the RApid Belt-driven Irradiated Target Transfer System (RABITTS). Yields were determined for 78 isotopes and isomers, covering the mass range 84≤A≤148 and the charge range from 33(As)≤Z≤58(Ce). Our experimental cumulative yields are compared to the literature and evaluated data at En≈0.5 MeV from ENDF/B-VIII.0 and JEFF-3.3 libraries and with theoretical models using the gef and freya codes at En=4.6 MeV.
