2015Pr10: 70Co produced in fragmentation of a 76Ge beam at E=130 MeV/nucleon on a 9Be target separated with the A1900 fragment separator and identified through ΔE-tof measurements. Measured Eγ, Iγ, βγ, β(t), βγ(t) using 16 detectors of the segmented Ge array (SeGA) for γ’s and a planar Ge double-sided strip detector for β’s. Measured T1/2 from time correlation between implantation events and β events in the planar Ge, including decay curves gated by γ rays.
2011Da08: 70Co produced in fragmentation of a 86Kr beam at E=57.8 MeV/nucleon on a natural Ta target. Isotopes separated with the LISE2000 spectrometer and identified through ΔE and time-of-flight measurements. Measured T1/2 from time correlation between implantation and β events in a DSSD detector.
2005NiZZ: 70Co produced in fragmentation of a 86Kr beam at E=63 MeV/nucleon on a 9Be target. Reaction products separated with the RIPS spectrometer and identified using trajectory, ΔE, and tof measurements using 4 position sensitive PPACs, a single-sided strip detector and two scintillators. Measured T1/2 using implant-β(t).
2003So21: 70Co produced in fragmentation of a 76Ge beam at E=61.8 MeV/nucleon on a 58Ni target. Isotopes separated with the LISE3 spectrometer and identified through ΔE and time-of-flight measurements. Measured T1/2 from time correlation between implantation and β events in a DSSD detector.
2003Sa40: 70Co produced in fragmentation of a 86Kr beam at E=58 MeV/nucleon on a natural Ta target. Isotopes separated with the LISE2000 spectrometer and identified through ΔE, total E and time-of-flight measurements. Measured T1/2 from time correlation between implantation and β events in a DSSD detector.
2000Mu10: 70Co produced in proton-induced fission of 238U with E=30 MeV. Isotopes separated using the LIGLIS-LISOL ion-guide laser-ion source and mass separator. Measured T1/2 using γ(t).
1998Am04: 70Co produced by fragmentation of a 86Kr beam with E=500 MeV/nucleon on a Be target. Isotopes separated with the FRS and identified by Bρ-ΔE-time-of-flight measurements. Measured T1/2 from time correlation between implantation and β events in a Si detector.
1985Gu14: 70Co first produced in the fragmentation of a 86Kr beam with E=33 MeV/nucleon and identified through time-of-flight and ΔE-E measurements.
