| 0 | < 25 ns % p = ? | S(p)=-2450 200 (syst, 2021Wa16) suggests that 33K is unbound for one-proton emission. E(level): S(p)=-2450 200 (syst, 2021Wa16) suggests that 33K is unbound for one-proton emission. |
1996PoZZ: re-analysis of upper limits for T1/2 (1986La17) obtained at LISE (GANIL). Unbound for one-proton emission.
1986La17: 58Ni(40Ca,X),E=77.4 MeV/nucleon 40Ca beam was produced at GANIL. Target was 68% enriched 58Ni. Reaction products were identified using the LISE spectrometer.
