General Comments:

2001Gi01, 2001Gi02: Ni(58Ni,X) E=74.5 MeV/α. Fragments selected by the α-LISE3 separator with a 10.4 mg/cm2 shaped Be degrader and Wien filter at GANIL. Ions implanted in a 5 Si-detector telescope which measured ΔE, E, and position. With tof measurements started both by the cyclotrons’ high-frequency and a micro-channel plate detector before the Wien filter, implanted ions could Be identified. The telescope was surrounded by Ge detectors to measure γ’s in the radioactive decay. Six 49Ni events observed. No evidence of 2p decay and no pγ coincidences observed.

2007Do17: Ni(58Ni,X) E=74.5 MeV/nucleon. α-LISE3 fragment separator. Fragment identification by energy loss, residual energy and tof 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. γ’s detected by four Ge detectors. Coincidences measured between charged particles and γ’s. T1/2 measured by time correlation of implantation events due to 49Ni and subsequent emission of protons and γ’s.
