1976Vi02 (also 1979ViZY thesis): 53Ni produced and identified in 40Ca(16O,3n),E=60,65 MeV at LBNL cyclotron facility. Measured half-life from decay curve of 1.94 MeV proton group
1993Xu04: 53Ni produced in 28Si(28Si,X),E=104.0-127.2 MeV; measured delayed-proton spectrum; deduced half-life
1994Bl10: production of 53Ni in 9Be(58Ni,X),E=650 MeV/nucleon, measured cross section using FRS at GSI facility
2007Do17: fragmentation reaction used to produce 53Ni isotope at SISSE/LISE3 facility in GANIL. Primary beam: 58Ni26+ at 74.5 MeV/nucleon; target=natural Ni. Fragment separator=α-LISE3. Fragment identification by energy loss, residual energy and time-of- flight measurements using two micro-channel plate (MCP) detectors and Si detectors. Double-sided silicon-strip detectors (DSSSD) and a thick Si(Li) detector were used to detect implanted events, charged particles and β particles. The γ rays were detected by four Ge detectors. Coincidences measured between charged particles and γ rays. T1/2 measured by time correlation of implantation events due to 53Ni and subsequent emission of protons and γ rays. Total proton branching ratio is from time spectrum of events with energy >900 keV in the charged-particle spectrum. Possible small contributions from delayed-α and delayed-2p decays are ignored.
2012Zh34 (also 2013Ya03): precise mass measurement at HIRFL-CSR facility in Lanzhou using isochronous mass spectrometry technique, mass excess=-29631 25
2013Su07: 58Ni primary beam at E=68.6 MeV/nucleon provided by the Heavy Ion Research Facility in Lanzhou (HIRFL). Target=147 μg/cm2 Ni at the Radioactive Ion Beam Line in Lanzhou (RIBLL). Measured β-delayed protons, (proton)γ-coin, Eγ, Iγ, time-of-flight, energy loss, T1/2 using two plastic scintillator films, a thick silicon detector, a double-sided silicon strip detector (DSSSD) and five segmented clover detectors. Performed nucleosynthesis calculations of rapid proton-capture process in an x-ray burst.
