Mass measurement of cooled neutron-deficient bismuth projectile fragments with time-resolved Schottky mass spectrometry at the FRS-ESR facility

Masses of 582 neutron-deficient nuclides ( 30 ⩽ Z ⩽ 85 ) were measured with time-resolved Schottky mass spectrometry at the FRS-ESR facility at GSI, 117 were used for calibration. The masses of 71 nuclides were obtained for the first time. A typical mass accuracy of 30 μu was achieved. These data ha...

Zusammenfassung:Masses of 582 neutron-deficient nuclides ( 30 ⩽ Z ⩽ 85 ) were measured with time-resolved Schottky mass spectrometry at the FRS-ESR facility at GSI, 117 were used for calibration. The masses of 71 nuclides were obtained for the first time. A typical mass accuracy of 30 μu was achieved. These data have entered the latest atomic mass evaluation. The mass determination of about 140 additional nuclides was possible via known energies ( Q-values) of α-, β-, or proton decays. The obtained results are compared with the results of other measurements.
