      abstract     = {The beta(+)- emitting radionuclide Y-86g (t(1/2) = 14.7 h)
                      forms a matched -pair with the beta(-)-emitting therapeutic
                      radionuclide Y-90 (t(1/2) = 2.7 d) for theranostic
                      application in medicine. Precise knowledge of the positron
                      emission probability of the PET nuclide is very important,
                      which was rather uncertain for Y-86g until recently. In this
                      work, an Y-86g source of high radionuclidic purity was
                      prepared and the positron emission intensity per 100 decay
                      of the parent (hereafter "positron emission intensity") was
                      determined by measuring the 511 keV annihilation gamma-ray
                      using high-resolution HPGe detector. The total source
                      activity was obtained from known gamma-ray emission
                      probabilities. The electron capture (EC) intensity was also
                      determined as an additional check by measuring the K-alpha
                      and K beta X-rays of energies 14.1 and 15.8 keV,
                      respectively, using a low energy LIPGe detector. From those
                      measurements, normalized values of 27.2 +/- $2.0\%$ for
                      beta(+)-emission and 72.8 perpendicular to $2.0\%$ for EC
                      were deduced. These results are in excellent agreement with
                      values recently reported in the literature based on a
                      detailed decay scheme study.},
