2001Gi10: 55Zn produced and identified in Ni(58Ni,X),E=74.5 MeV/nucleon reaction using SISSI/LISE3 facility of GANIL. α total of 17 counts were assigned to 55Zn. Measured production σ of 20 pb +6-5
2007Do17: 55Zn produced and identified in fragmentation of 74.5 MeV/nucleon 58Ni26+ beam with nickel target using SISSE/LISE3 separator facility in GANIL. 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 55Zn 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.
2021Ku30: 55Zn production σ measurement in 9Be(78Kr,X), E=345 MeV/nucleon reaction using BigRIPS separator at the RIBF-RIKEN facility.
Theoretical calculations: 13 primary references (seven for structure and six for 55Zn decay) retrieved from the NSR database at www.nndc.bnl.gov/nsr/. These are listed in this dataset under ’document’ records.
Q-value: Estimated uncertainties (2021Wa16): 450 for S(n), 570 for S(p), 640 for Q(α).
