Additional Level Data and Comments:
| E(level) | Jπ(level) | T1/2(level) | Comments |
| 0 | (3/2-) | < 81 ns % ε = ? % p = ? | Evidence for proton decay and unbound character of 73Rb g.s. found by 1996Jo17, but percent decay mode was not deduced. |
| 3.23E3 | (1/2-) | % p = 100 | T=3/2 This level decays by protons to 72Kr g.s. E(level): This level decays by protons to 72Kr g.s. |
1996Pf01: 73Rb produced in 58Ni(78Kr,X), E=75 MeV/nucleon, tof analysis.
1996Jo17: 73Rb produced in 93Nb(p,X), E=1 GeV; yield measurement
2005Ro39: deduced mass excess from measurement of mass excess for mirror nucleus 73Kr at ISOLDE-CERN. No events were seen for 73Rb. Deduced upper limit of half-life of 73Rb decay
2017Su31: 9Be(124Xe,X),E=345 MeV/nucleon. Measured β(fragment) correlated events using BigRIPS and ZeroDegree Spectrometer for the separation and tagging of nuclei by Bρ-tof-ΔE technique at RIBF-RIKEN facility. The ion beam was implanted into the active silicon stopper WAS3ABi with subsequent detection of β+, proton-delayed γ-rays by the EURICA HPGe detector array. Deduced upper limit of half-life of 73Rb g.s. decay.
Q-value: Estimated uncertainties (2017Wa10): 450 for Q(β-), 540 for S(n), 200 for S(p), 210 for Q(α)
Q-value: S(2n)=30160 450, S(2p)=4160 200, Q(εp)=5690 200 (syst,2017Wa10)
