General Comments:

1985Gu14: activity produced by fragmentation of 33 MeV/nucleon 86Kr beam on thick Ti and Ta targets and subsequent particle analysis with a spectrometer having a charge resolution ΔZ/Z<1.5% and mass resolution ΔA/a<1%. Obtained mass histograms

1990Tu01: activity produced by 800 MeV proton-induced fission and fragmentation using natural Th target and subsequent particle analysis with a tof isochronous spectrometer.

1998Am04 (also 1997AmZZ thesis): 57Ti activity produced by fragmentation of a 500 MeV/nucleon beam of 86Kr on a thick 9Be target and subsequent mass separation in the FRS spectrometer at GSI . facility. Measured T1/2.

1996Do23: activity produced by fragmentation of a 64.5 MeV/nucleon beam of 65Cu on a 9Be target and subsequent mass separation in the LISE3 spectrometer at GANIL facility. Measured T1/2 using β and βγ coincidences.

1998Am04: 57Ti produced in the fragmentation of 500 MeV/nucleon 86Kr beam on a 9Be target and subsequent mass separation using the FRS spectrometer at GSI. Measured T1/2. See also 1997AmZZ thesis

1999So20 (also 1999Le67): 57Ti produced at GANIL in fragmentation of 86Kr34+ beam with 58Ni target followed by separation of fragments using LISE3 spectrometer. Measured half-life of g.s. from β and γ-ray studies.

2005Li53: 57Ti isotope produced in fragmentation of 86Kr34+ beam on a 9Be target. Secondary fragments were selected using the A1900 fragment separator. Fragment identification was performed by a combination of multiple energy-loss signals and time of flight method. Measured Eγ, Iγ, γγ, γβ(t), lifetime with 12 Ge detectors from the MSU segmented Ge array and double-sided Si microstrip detector.

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔS(p)=830, ΔQ(α)=680 (syst,2009AuZZ,2003Au03)

Q-value: Q(β-n)=4460 500, S(2n)=8020 480, S(2p)=30000 830 (syst) (2009AuZZ,2003Au03)
