General Comments:

1993So06, 1995So03: 64Ni(48Ca,X) E=60 MeV/α; mass separation. Measured T1/2, β-n coincidences, and delayed-neutron emission probability (doubly-achromatic spectrometer; polyethylene-moderated 3He pc’s)

1998WiZV: Be(48Ca,X) E=70 MeV/α and 80 MeV/α. Mixed-particle beam produced by fragmentation of 48Ca beams provided by the K1200 cyclotron at the NSCL of Michigan State University on 254 mg/cm2 and 376 mg/cm2 Be targets, respectively. Ions identified with a thin Si detector before implantation into Al targets. Measured γ’s and γγ- and βγγ-coincidences. Changes in the beam-on/beam-off timing cycle and beam-line tuning allowed association of γ’s to specific decays and T1/2 measurements.

Gammas: See (46Ar,2pγ) for unplaced γ

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

Q-value: Q(β-n)=6.24 MeV 12 (2003Au03)

Q-value: Δ’(45Cl)=-18.36 MeV 12 (2003Au03) compared to -18.36 MeV 10 (2007Ju03. See 2000Sa21 for experimental details)
