1997Be70: 86Ga produced and identified in 9Be(238U,F) reaction at E=750 MeV/nucleon at GSI. Identification by Fragment-Recoil Separator (FRS) and time-of-flight. α total of 4 events were assigned to 86Ga.
2013Mi19, 2014Gr03: proton beam was provided by the Oak Ridge Isochronous Cyclotron (ORIC) at the HRIBF-ORNL facility. Target=UCx. Mass analyzed ions of 86Ga were extracted using Resonant Ionization Laser Ion Source (RILIS). Pure 86Ga beam was then sent to the Low-energy Radioactive Ion Beam Spectroscopy Station (LeRIBSS) and implanted in a moving tape collector (MTC). Measured Eγ, Iγ, Eβ, βγ-coin, nγ-coin, half-life of 86Ga, Pn, P2n using two HPGe Clover detectors, two plastic scintillation counters for β, and an array of 48 3He ionization chambers for neutron detection. Comparison of measured half-life, P1n and P2n with predictions from several calculations such as FRDM+QRPA, FRDM+QRPA2, DF3a+CQRPA, DF3a+CQRPA+fragmentation of β strength; FRDM=finite range droplet model, CQRPA=continuum quasiparticle random phase approximation; DF=density functional.
Q-value: ΔQ(β-)=ΔS(n)=760, ΔS(p)=990, ΔQ(α)=1060 (syst,2012Wa38)
Q-value: S(2n)=6320 810, Q(β-n)=10600 700 (syst,2012Wa38). S(2p)=34850 (calculated, 1997Mo25)
