2007Ba71: W(48Ca,Xγ) E=141 MeV/nucleon beam from the National Superconducting Cyclotron Laboratory (NSCL). The fragments were separated with the A1900 fragment separator. Isotopic identification by multiple ΔE signals, magnetic rigidity, total energy and time of flight analysis. Detectors: plastic scintillators, parallel-plate avalanche counters (PPACs) and silicon PIN diodes.
In 2007Ba71, a total of 23 events were assigned to 42Al, establishing particle stability of this nuclide.
Q-value: Estimated uncertainties (syst,2012Wa38): ΔQ(β-)=780, ΔS(p)=1034, ΔS(n)=840
Q-value: S(p) and Q(α) from 1997Mo25; Q(β-) and S(n) from 2012Wa38. Theoretical S(n)=-2610 (1997Mo25) differs much from 1120 840 (syst,2012Wa38)
Q-value: S(2n)=3280 780, Q(β-n)=20650 700 (syst,2012Wa38). Theoretical S(2p)=53610 (1997Mo25)
