First identification of 43Cr nuclide by 1992Bo37
1992Bo37: 43Cr produced by Ni(58Ni,X) E=69 MeV/nucleon, followed by measurement of fragment spectra. Measured β+p, E(p), I(p), T1/2.
1994Bl10: 43Cr produced by 9Be(58Ni,X) E=600 MeV/nucleon. Measured production cross sections.
2001Gi01, 2001Gi02: 43Cr produced by Ni(58Ni,X) E=74.5 MeV/nucleon. Selected isotopes implanted in a ΔE-E silicon detector telescope. Measured T1/2, E(p), I(p)
2007Do17: E=74.5 MeV/nucleon 58Ni was produced at the SISSI-LISE3 facility of GANIL, incident on a natural nickel target of 250 mg/cm2. Fragments were selected by the α-LISE3 separator, identified by two micro-channel plate (MCP) detectors and detected in a detection setup consisting of silicon and germanium detectors. Measured β-delayed proton and γ spectra, branching ratios, half-life.
2011Po01: E=161 MeV/nucleon 58Ni beam was produced at the NSCL, MSU, incident on a target of 800 mg/cm2 natural nickel foil. Reaction products were separated by the A1900 fragment separator and identified by time-of-flight (tof) and energy-loss. Decays were detecte using the Optical Time Projection Chamber (OTPC). Measured Ep, Ip, branching ratios for difference decay modes. Deduced half-life.
2012Au08 (also 2012As02): 43Cr nuclei produced in the reaction Ni(58Ni,X), E(58Ni)=75 MeV/nucleon using LISE3 separator at GANIL 43Cr ions were separated, identified and then implanted onto the time projection chamber (TPC). Decays were detected in a time-projection chamber (TPC), where signals from four gas electron multipliers (GEM) detected in a two-dimensional strip detector combined with drift-time analysis were used to reconstruct the tracks of the particles in three dimensions. Characterization of the TCP was done with the β+p decay of 52Ni with reference to proton energies and branching ratios. Measured energy loss, decay events, angular correlation between two protons. Deduced delayed one-, two-, and three-proton decay branching ratio. Implantation and decay events were time correlated. Recorded events in this study: 180 events for β+2p emission, and three events for β+3p emission from decay of 43Cr
