Abstract: The mass yield distribution of fission products produced in the photofission of 238U using 9 MeV bremsstrahlung have been radiochemically measured for 21 mass chains. The absolute activities of the nuclides measured were determined from gross β counting and total chain yields were measured relative to 99Mo. The peak to valley ratio was found to be about 310, which is comparable with previous results measured at 10 MeV. Fine structure was found to be a prominent feature and occurred around mass number 133, although mass number 134 could not be measured in the present investigation. The fission yields measured in this work have been compared to all known existing values for work in photon energy range of 9 ± 1 MeV.
