Q(β-)=1.34×104 keV SYS(n)= 2.8×103 keV SYS(p)= 1.91×104 keV SYQ(α)= -1.49×104 keV SY
Reference: 2012WA38

General Comments:

1997Be70: 71Fe produced and identified in 9Be(238U,X) reaction at 750 MeV/nucleon followed by mass separation in a magnetic spectrometer, time-of-flight and energy loss measurements. Measured production cross section.

2002MaZN (thesis): 71Fe produced in fragmentation of 86Kr beam at 57.8 MeV/nucleon at GANIL facility, LISE 2000 fragment separator, time-of-flight method, EXOGAM array for γ-ray detection. Measured β, isotopic half-life

Q-value: Note: Current evaluation has used the following Q record

Q-value: Q(β-), S(n) and Q(α) from 2009AuZZ and 2003Au03; S(p) from 1997Mo25

Q-value: Δ(Q(β-))=1160, Δ(S(n))=1000, Δ(Q(α))=1060 (2009AuZZ,2003Au03)

Q-value: S(2n)=8750 950 (syst), Q(β-n)=6570 1160 (syst,2009AuZZ,2003Au03)
