General Comments:

First isotope identification by 1976Be08

1980Ew02: 45Sc(p,8N3p)35K at Ep=600 MeV from the synchrocyclotron at the ISOLDE facility at CERN on a 13.6 g/cm2 ScC2 target. α 109 cm3 Ge(Li) detector (FWHM=2.1 keV at 1.33 MeV) for detecting gammas and a telescope (FWHM=50 keV) of two surface barrier detectors (ΔE: 20 μm, 50 mm2 and E: 700 μm, 150 mm2) for detecting protons. Measured Eγ, Iγ, Ep, Ip, T1/2. Deduced log ft, levels for 35Ar.

1990De43, 1992Mo15: 39Ti(β+α)35K. Measured β-delayed charged particle spectra.

1998Sc19: Fragmentation of a 500 MeV/nucleon 40Ca beam from the GSI synchrotron SIS on a 4 g/mc{=2 9Be target. Measured fragment β asymmetry, T1/2. Deduced g-factor.

Mass measurements: 2007Ya08, 1976Be08
