  A  86Ga β- decay (43 MS) 

General Comments:

1994Be24: 86Ge produced and identified in Pb(238U,F) reaction at E=750 MeV/nucleon at the SIS synchrotron, GSI. Identification using the Bρ-ΔE-tof method and FRS separator

2013Ma22: proton beam was provided by the Oak Ridge Isochronous Cyclotron (ORIC) at the HRIBF-ORNL facility. Target=238UCx. Fission fragments were ionized to charge state +1 then purified using H2S gas, a mass pre-separator and electromagnetic separation. The purified beams were 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, half-life of 86Ge g.s. using two plastic scintillation counters and four HPGe detectors. Comparison with the gross theory of β decay, the finite-range droplet model and the continuum quasiparticle random-phase approximation.
