Table 1.
Production yield of 82Br, 80mBr, 76Br, and 77Br from various isotopic compositions of CoSe targets at four proton energies (Ep). Reported uncertainties represent standard deviations of multiple irradiations or are estimated when n=1. Limits of detection calculated from HPGe spectra [29] are reported. In some cases (denoted as n/a), HPGe measurements were too late to quantify short-lived 80mBr.
