General Comments:

2016Ca25, 2017Ca12: 215Tl produced in 9Be(238U,X) reaction with E = 1 GeV/nucleon produced by the SIS synchrotron at GSI. Fragments were separated and identified by GSI Fragment Separator (FRS) using Bρ-ΔE-Bρ technique. Measured betas, neutrons, β-n, β(t) using BELEN (BEta-deLayeEd Neutron) array consisting of 30 3He tubes embedded in polyethylene.

2010Al24: 215Tl nuclide produced in 9Be(238U,X) reaction with E = 1 GeV/nucleon produced by the SIS synchrotron at GSI facility. Fragments were analyzed with the Fragment Recoil Separator (FRS) and identified using magnetic rigidity, velocity, time-of-flight, energy loss and atomic number of the fragments

2004DeZV: authors mention using RILIS ionization source to study the 215Tl activity using βγγ coincidence setup, however, no resonant γ rays were seen. Probably, the 215Tl activity was not formed in this study

Q-value: Estimated uncertainties: ΔQ(β-)=310, ΔS(n)=360, ΔS(p)=500 (2021Wa16)

Q-value: Q(β-n)=2140 300, S(2n)=7900 300 (syst,2021Wa16).
