  1. Mass and Half-Life Measurements of Stored Exotic Nuclei Yu.A. Litvinov, Hirschegg 19.01.2006

  2. Present Knowledge of Atomic Masses

  3. Experimental facility at GSI Highly-Charged Ions In-Flight Separation Cocktail or Monoisotopic Beams

  4. Schottky Mass Spectrometry (SMS)

  5. Broad-band Schottky frequency spectra

  6. About 1/3 of all known masses were covered in one experiment Typical mass accuracy 1.5 10-7 Mass resolving power 2 106 reached 275 new masses determined More than 300 improved values Measured Mass Surface Yu.A. Litvinov et al., Nucl. Phys. A756 (2005) 3

  7. Predictive Powers of Mass Models

  8. Two new SMS experiments Identification, Mass and Half-life values in one experiment

  9. Isohronous Mass Spectrometry (IMS)

  10. m/q range is 2.4-2.7 Time-of-Flight Spectra

  11. Isochronicity curves for several mass-to-charge ratios

  12. Improved resolving power

  13. 238U Fission Fragments M. Matos, PhD Thesis, JLU Giessen 2004
