State-of-the-art γ-ray assay of ⁸⁶Y for medical imaging

RADIOACTIVITY ⁸⁶Y(β⁺), (EC)[from ⁸⁶Sr(p, n), E=16 MeV at the University of Wisconsin Medical Physics cyclotron, followed by chemical separation of activity]; measured Eγ, Iγ, γγ-coin, γγ(θ) using the Gammasphere array at ANL. ⁸⁶Sr; deduced levels, J, π, multipolarities, mixing ratios, I(β⁺+ϵ), logft values, maximum and average positron energies; estimated radiation dose for potential imaging partner to the therapeutic ⁹⁰Y isotope. Comparison with previous experimental results.
