Spectroscopy of the long-lived excited state in the neutron-deficient nuclides ^{195, 197, 199}Po by precision mass measurements

ATOMIC MASSES ^{195,195m,196,197,197m,199m,203,208}Po; measured cyclotron frequency ratios, mass excesses using ISOLTRAP Penning-trap mass spectrometer at ISOLDE-CERN. The Po isotopes produced in U(p, X), E=1.4 GeV using RILIS and high-resolution mass spectrometer. ^191m,193mPb, ^195m,197mPo, ^199m,201mRn, ^203m,205mRa; deduced level energies of 13/2+ isomers in odd-A polonium isotopes from mass measurements, and other isomers from α decay. Comparison with evaluated data in AME-2016.

RADIOACTIVITY ^{195,195m,197,197m,199m}Po(α)[from U(p, X), E=1.4 GeV using RILIS and high-resolution mass spectrometer at ISOLDE-CERN]; measured Eα, Iα.
