1983Ru06: produced by 76Ge on W, E=9 MeV/nucleon, on-line mass separation and tape-transport system; measured half-life
1999Pr10: production in 76Ge fragmentation
2008St01: E=1 GeV proton beam provided by CERN PS booster. 71Cu beam was obtained using the ISOLDE fragment separator and implanted in the NICOLE detector system. The refrigerator temperature was varied between 1 K and 11-12 mK. Measured nuclear dipole moment of g.s. using β-NMR method on oriented nuclei at low temperatures.
2009Fl03: In-source laser spectroscopy and collinear laser spectroscopy at CERN, ISOLDE facility. Measured spin and static magnetic moment of ground state
2010Vingerhoets: in a paper by p. Vingerhoets et al. (accepted for publication in Phys. Rev. C on Nov 29, 2010) the authors have measured spin, static magnetic moment and static quadrupole moment using Colliner laser spectroscopy technique and hyperfine structure at ISOLDE-CERN facility
Mass measurement: 2007Gu09
2010Si11, 2010Da06: shell model calculations of low-lying states
Q-value: Note: Current evaluation has used the following Q record
Q-value: Q(β-)=4616 10 (2003Au03), others same as in 2009AuZZ
Q-value: S(2n)=13117.5 20, s(2p)=27290 340 (2009AuZZ,2003Au03)
