      abstract     = {The β+-emitting radionuclide 86gY (t1/2 = 14.7 h) forms a
                      matched-pair with the β−-emitting therapeutic
                      radionuclide 90Y (t1/2 = 2.7 d) for theranostic application
                      in medicine. This approach demands a precise knowledge of
                      the positron emission probability of the PET nuclide which
                      was until recently rather uncertain for 86gY. In this work,
                      an 86gY source of high radionuclidic purity was prepared and
                      a direct measurement of the positron emission intensity per
                      100 decay of the parent (hereafter “positron emission
                      intensity”) was performed using high-resolution HPGe
                      detector γ-ray spectroscopy. The electron capture intensity
                      was also determined as an additional check by measuring the
                      Kα and Kβ X-rays of energies 14.1 and 15.8 keV,
                      respectively, using a low energy HPGe detector. From those
                      measurements, normalized values of 27.2 ± $2.0\%$ for
                      β+-emission and 72.8 ± $2.0\%$ for EC were obtained. These
                      results are in excellent agreement with values recently
