General Comments:

2009Ta05,2009Ta24: 70Mn produced in fragmentation of 76Ge beam at 132 MeV/nucleon on Be and W targets. Separated using A1900 fragment separator and S800 to form a two-stage separator system. Unambiguous identification of 70Mn using multiple ΔE, magnetic rigidity, total energy and time-of-flight measurements. ΔE measured with a stack of eight Si PIN diodes and time of flight measured in four ways using plastic scintillators, Si detectors, and parallel-plate avalanche counters. Measured cross section=20×10-12 mb +10-14 (read by the evaluators from figure 2 of 2009Ta05).

2015Be32: 70Mn produced in in-flight fission of a 238U beam at E=345 MeV/nucleon on a Be target and separated with the Big-RIPS separator combined with the ZeroDegree Spectrometer. Measured Eγ, Iγ, βγ, β(t), βγ(t) using the 5 silicon detectors of the WAS3ABI array which was surrounded by the EURICA spectrometer consisting of 12 HPGe EUROBALL cluster detectors and 18 small volume LaBr3(Ce) scintillators.

Q-value: ΔQ(β-)=860; ΔS(n)=920; ΔQ(α)=920 (2012Wa38)

Q-value: S(2n)=7060 syst 860; Q(β-n)=11770 syst 810 (2012Wa38).
