^aFor the 72 MeV ¹⁶O experiment, counting did not begin until approximately 18 h EOB. Consequentially, any ⁷⁷Kr produced would have decayed to a level too low to be detected prior to gamma spectroscopy beginning. The measured ⁷⁷Br therefore represents both directly produced ⁷⁷Br and the product of ⁷⁷Kr decay. For both isotopes, the predicted activities are for physical yield at EOB (using the same delivered current profile as the actual irradiation). The effects of simulation error on the predicted yields are negligible compared to variations in delivered beam and are ignored.
^bThe 37.7 kBq of ⁷⁷Br represents the predicted EOB activity that would be found if all ⁷⁷Kr produced was allowed to decay to ⁷⁷Br, and then an EOB activity for ⁷⁷Br was determined by backfitting the decay from that point forward without decay-correcting for ⁷⁷Kr feeding.
