Delayed-neutron branching ratios in the fission product region have been tabulated, and average values have been determined. In order to provide data complementary to published values an experiment covering the mass range 79-150 has been carried out at the OSIRIS isotope-separator on-line facility at Studsvik. This experiment has resulted in branching ratios for some precursors (84Ge, 133Sn, and 150La) for which such data have not been reported before. In several other cases the new results are more accurate than older determinations. |
