  1. aTo account for indirect production, physical yields for the heavy-ion reaction are given for 4 h EOB, to allow ~ 90% of the 77Kr to decay to 77Br.
  2. bSince 3-h irradiations were not performed, the absolute yields are scaled from physical yield (accounting for saturation and decay effects) and reported per-particle-microamp of beam delivered (the proton data assumed a 40 μA max current for the entirety of the run). The 55 MeV data are based on data reported in this work. The 72 MeV data are a prediction from PACE calculations, since the measured data were likely depleted by krypton evaporation.
