2011Da08,2002MaZN (thesis): Produced by projectile fragmentation of 86Kr beam on 50 mg/cm2 thick Ta at 57.8 MeV/nucleon. Separated by LISE2000 spectrometer at GANIL. Detector system included a three-element Si-detector telescope containing a double-sided silicon-strip detector (DSSSD) backed by a Si(Li) detector and surrounded by four clover type EXOGAM Ge detectors. Product identified by mass, atomic number, charge, energy loss and time of flight. Measured isotopic T1/2 from timing correlation between implanted ions and β decay events. Fitting procedure included five parameters: β-detection efficiency, background rate, mother, daughter and granddaughter half-lives.
2010Sc18: Summary and compilation of the discovery of Fe isotopes.
2003So21,2005GaZR (thesis): Produced by fragmentation of 76Ge30+ beam on a 58Ni target at 61.8 MeV/nucleon. Nuclei separated by LISE3 achromatic spectrometer at GANIL, and identified by three consecutive Si detectors where two were used for energy loss and time-of-flight measurements while the third was used to determine their residual energies. Measured isotopic T1/2 from correlations between implanted nuclei and β decay.
2003So02: Produced by fragmentation of 76Ge30+ beam on a 58Ni target at 61.8 MeV/nucleon. Nuclei separated by LISE3 achromatic spectrometer at GANIL.
1998Am04,1997AmZZ: Produced by fragmentation of 86Kr beam on a Be target at 500 MeV/nucleon. Fission fragments separated with the FRS separator at GSI and identified by combination of Bρ, Z, and tof techniques. Measured isotopic T1/2 from timing correlations of implanted fragments and β decay.
1992We04: Produced by fragmentation of 86Kr beam on a Be target at 500 MeV/nucleon. Isotope identification by the fragment separator FRS at GSI in combination with tof and energy-loss measurements. α total of 12 counts were assigned to 69Fe corresponding to cross section of 2.5 nanobarns with an uncertainty of 80%.
