89Ru identified by 1992Ye04 in 58Ni(92Mo,X) E=70 MeV/nucleon followed by fragment mass separation and tof (≈150 ns) techniques
2001Ki13 (also 2002Fa13,2007WeZX): 89Ru produced in fragmentation of 112Sn beam in 9Be(112Sn,X) reaction at E=1 GeV/nucleon, followed by mass separation. Measured half-life and yield. Other reports from the same group: 2000WeZZ, and E. Wefers et al., GSI annual (2000) report 2001-1, p10
1999Li33 reported delayed-proton decay from 89Ru formed in reaction 58Ni(36Ar,2p3n) at 220 MeV and transported by He jet system, no mass separation was employed. The authors measured half-life of 1.2 s 2 from (proton)(γ in 88Mo) coin and observation of 741γ and 914γ assigned to 88Mo.
2004De40 also used reaction 58Ni(36Ar,2p3n) at E=235, 255 MeV followed by mass separation. The authors did not observe any evidence for the formation of 89Ru and its εp decay or the existence of 741γ that was reported by 1999Li33. 2004De40 suggested that 741γ seen by 1999Li33 may be from ε decay of 89Tc. An upper limit of %εp=0.15 was deduced by these authors.
2012Lo08: 89Ru produced from fragmentation of a 112Sn beam at E=120 MeV/nucleon on a 195 mg/cm2 9Be target at the National Superconducting Cyclotron Laboratory (NSCL). Fragments separated by the A1900 Fragment Separator and the Radio Frequency Fragment Separator (RFFS). Ions were implanted in the double-sided silicon strip detector (DSSD). Detection system: NSCL Beta Counting System in conjunction with the SeGA Array of 16 HPGe detectors. Measured Eγ, Iγ, β spectra, E(p), I(p), βγ-coin, βp-coin, γβp-coin, half-life, β-delayed proton emission probability. α total of 167 89Ru ions implanted in DSSD and six βp coin events identified.
2019Pa16: 89Ru produced in 9Be(124Xe,X),E=345 MeV/nucleon followed by separation of fragments of interest using BigRIPS and ZeroDegree spectrometer, and separated ions implanted in WAS3ABi stopper and detector system at RIBF-RIKEN. The γ rays from the decay of 89Ru were detected using the EURICA array of 12 cluster Ge detectors. Measured half-life of 89Ru decay from (implants)β-correlated distribution and β+-delayed proton emission probability.
2019Vi05: measured mass excess of g.s. of 89Ru using time-of-flight ion-cyclotron resonance (tof-ICR), and phase-imaging ion-cyclotron resonance (π-ICR) techniques at the University of Jyvaskyla accelerator facility
1992MoZV and 1993MoZR are by the same group as 1992Ye04
