1995Bl06: 74Sr produced and identified at GANIL in Ni(78Kr,X) E=73 MeV/nucleon reaction, time-of-flight method
2014He29: 74Sr produced in 40Ca(36Ar,2n),E(36Ar)=105 MeV reaction at Jyvaskyla K130 cyclotron facility. Measured Eγ correlated with implanted recoils, or with charged particles. Recoil-β tagging technique.
2005Ro39: deduced mass excess=-40830 keV 100 from measured mass excess of mirror nucleus 74Kr using ISOLTRAP at ISOLDE-CERN
Q-value: Estimated uncertainties (2012Wa38): 410 for S(n), 140 for S(p)=140, 220 for Q(α)
Q-value: S(2p)=1470 100, Q(εp decay)=8440 100 (syst,2012Wa38). S(2n)=31700 (theory,1997Mo25)
