2001Gi10: 56Zn produced in Ni(58Ni,X),E=74.5 MeV/nucleon, with 230.6 mg/cm2 thick target. Fragments were identified by ΔE and tof following SISSI and LISE3 fragment separators at GANIL. α total of 17 events were assigned to 56Zn, implying production σ=0.5 nb +20-2.
2007Bl09: 56Zn produced in Ni(70Ge,X),E=71.6 MeV/nucleon, followed by separation of fragments using LISE3 separator at GANIL. About 20 events, assigned to 56Zn are displayed in fragment identification plot in Fig. 1 or 2007Bl09.
2007Do17: Ni(58Ni,X),E=74.5 MeV/nucleon at 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 56Zn and subsequent emission of protons and γ rays. Total proton branching ratio arises 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.
2016Or03, 2014Or04 (also conference papers from the same experimental group: 2017RuZX, 2016Ru04, 2016OrZY, 2015Or02, 2014Ru08, 2014Or03, 2014OrZZ, 2012OrZY): 56Zn produced in fragmentation of 74.5 MeV/nucleon 58Ni beam on a 200 μm thick natural Ni target at LISE3-GANIL facility. Fragments were selected by LISE3 separator and implanted into a double-sided silicon strip detector (DSSSD), surrounded by four EXOGAM Ge clovers for γ ray detection. Implantations were identified by energy loss ΔE and time-of-flight (tof) information. Measured Ep, Ip, half-life of 56Zn decay, and delayed proton decay branches.
2021Ku30: 56Zn produced in 9Be(78Kr,X),E=345 MeV/nucleon. Measured production σ using BigRIPS separator at the RIBF-RIKEN facility
