| 0 | 103 ns 22 % ε = ? % p = ? | Proton decay mode of 72Rb is expected to be dominant, as S(p) value is negative from a systematic trend (2021Wa16), and theoretical T1/2(β decay)=28.4 ms (2019Mo01). E(level): Proton decay mode of 72Rb is expected to be dominant, as S(p) value is negative from a systematic trend (2021Wa16), and theoretical T1/2(β decay)=28.4 ms (2019Mo01). |
2017Su31: 72Rb nuclide produced and identified in 9Be(124Xe,X),E(124Xe)=345 MeV/nucleon fragmentation reaction at RIBF-RIKEN facility. Measured (implants)β correlated events using BigRIPS and ZeroDegree spectrometers for the separation and tagging of nuclei through event-by-event analysis to identify atomic number Z and α/q (atomic mass/charge) ratio by Bρ-tof-ΔE technique, Bρ measured using parallel-plate avalanche counters, tof by plastic scintillators, and ΔE by ionization chambers. The secondary ion beam was finally implanted into the active silicon stopper WAS3ABi with subsequent detection of β+, and proton-delayed γ-rays using the EURICA HPGe detector array. Deduced half-life of 72Rb g.s. decay. Total of 14 events were ascribed to 72Rb in the present experiment. Deduced half-life of 103 ns is consistent with its proton-unbound character with S(p)=-710 keV 520 (syst, 2017Wa10)
2019Si33: calculated g.s. configuration and compared with proton decay of 76Y.
Q-value: Estimated uncertainties (2021Wa16): ΔS(n)=640, ΔS(p)=520, ΔQ(α)=560
Q-value: S(2p)=1480 500, Q(ε)=15610 500, Q(εp)=10880 500 (syst, 2021Wa16). S(2n)=31180 (theory, 2019Mo01)
