Abstract:
Using quadruple coincidence events of prompt fission gamma rays from Gammasphere data on spontaneous fission of 252Cf, we made a careful analysis of the yield matrix of coincident pairs of barium (Z = 56) and molybdenum (Z = 42) fission fragments. The accuracy of previously determined yield matrices is improved upon with the use of high accuracy quadruple coincidences, the increased statistics of the most recent Gammasphere data, and improved level schemes for barium and molybdenum isotopes. The previously proposed extra hot fission mode (up to ten neutron evaporated) has been confirmed in our reanalysis. Our results are well in agreement with the results from the 1995 Gammasphere data analysis of the Ba-Mo yields.
