Mass-yield measurements were made for the fission of 241Am induced by graphite-moderated reactor neutrons. In most cases gamma-ray spectrometry was used to measure the radioactivity of the isolated fission products. The relative abundance of each nuclide representing a particular fission chain was determined radiochemically with respect to 139Ba, whose fission yield was assumed to be 6.22%. The composite results of the three separate experiments are presented.
