General Comments:

1998Pf02: 212Tl produced by fragmentation of a 1 GeV/nucleon beam of 238U on a beryllium target. The ions of 212Tl were separated and analyzed with the GSI FRagment Separator (FRS)

2010Al24: 212Tl nuclide produced in 9Be(238U,X) reaction with E(238U)=1 GeV/nucleon at GSI facility. Fragments were separated with the high resolving power magnetic spectrometer FRagment Separator (FRS) and identified based on measurements of magnetic rigidity, velocity, time-of-flight, energy loss and atomic number of the fragments using two plastic scintillators and two multisampling ionization chambers.

2012Be28: see 2010Al24 above for method of production at GSI facility; deduced T1/2.

2017Ca12,2016Ca25: 212Tl produced in 9Be(238U,F) reaction with E(238U)=1 GeV/nucleon and separated using the GSI FRagment Separator (FRS) using the Bρ-ΔE-Bρ technique. Ions were implanted into the SIMBA array consisting of a stack of double-sided silicon strip detectors. Measured β, β(t), βn using the BELEN array consisting of 30 3He tubes within polyethylene moderator and shielding. Preliminary results reported in 2016DoZZ.

Q-value: ΔQ(β-)=200; ΔS(n)=210; ΔS(p)=280; ΔQ(α)=360 (2017Wa10)

Q-value: S(2n)=8450 (syst) 200; S(2p)=18460 (syst) 450; Q(β-n)=870 (syst) 200 (2017Wa10).
