Production and identification:
1981Ew01: 71Kr produced and identified in 93Nb(p,X) at 1 GeV, chemical mass separation, measured half-life
1995Bl23: fragmentation of 78Kr beam at 73 MeV/nucleon with a carbon target. SISSI/LISE spectrometer at GANIL. Energy loss and time-of-flight techniques.
1997Oi01: 93Nb(p,X) at 1 GeV, ISOLDE-CERN facility, measured γ, β, delayed protons, coincidences between different types of radiation
2002Lo13 (also 2002Bl17): fragmentation of 78Kr beam at 73 MeV/nucleon with a carbon target. SISSI/LISE spectrometer at GANIL. Energy loss and time-of-flight techniques.
2008NaZR: Ca(32S,X) and Ca(33S,X), recoil-β+ decay tagging method to identify γ rays in 71Kr. The details are not available
1964Fl03: 70-72Br or 70-72Kr claimed to have been produced in Ni(20Ne,X) E=140 MeV reaction and a delayed proton group of 2.5 MeV with a half-life of 23 s 4. It is not possible to associate this observation with a presently known activity

Q-value: Note: Current evaluation has used the following Q record
Q-value: Uncertainties: ΔS(n)=760, ΔS(p)=720, ΔQ(α)=680 (syst,2009AuZZ)
Q-value: S(2n)=30630 770, s(2p)=5200 650, Q(εp)=7709 650 (2009AuZZ)
Q-value: Values in 2003Au03: S(n)=13320 760 (syst), S(p)=2790 720 (syst), Q(α) same as in 2009AuZZ, Q(εp)=7830 660
