Additional Level Data and Comments:
| E(level) | Jπ(level) | T1/2(level) | Comments |
| 0.0 | (7/2-) | 80 ms 3 % β- = 100 % β-n ≤ 6 2 | %β-n from estimate of intensity of 1259γ in 70Ni (2010RaZY, 2005Ma95). This γ ray is observed, thus delayed-neutron decay mode does occur. Note that 2005Ma95 stated %β-n|>3 1, which should have read |<3 1. |
1992We04: 71Co produced and identified by fragmentation of 500 MeV/nucleon 86Kr beam incident on a beryllium target followed by mass separation in a magnetic spectrometer using in addition time-of- flight and energy loss measurements for nuclide identification. Measured production cross section.
1998Am04 (also 1997AmZZ thesis): 71Co produced in the fragmentation of 86Kr beam at 500 MeV/nucleon with 9Be target at GSI facility. Fragment recoil separator used to separate fragments. Magnetic rigidity and time-of-flight method used to identify the isotope. Measured half-life
2004Sa59 (also 2002MaZN thesis): 71Co produced in the fragmentation of 86Kr beam at 57.8 MeV/nucleon with 181Ta target at ganil facility. Lise2000 spectrometer was used to separate fragments. Magnetic rigidity and time-of-flight method used to identify the isotope. Measured γ rays, βγ coin, half-life
2005GaZR thesis (also 2003So21 conference article): 71Co produced in the fragmentation of 76Ge beam at 61.8 MeV/nucleon with 58Ni target at ganil facility. Lise3 spectrometer was used to separate fragments. Magnetic rigidity and time-of-flight method used to identify the isotope. Measured β, half-life
2010RaZY (also 2005Ma95): 71Co produced in the fragmentation of 86Kr beam at 140 MeV/nucleon with a 9Be target, followed by separation using A1900 FRS at NSCL facility. Time-of-flight and E-ΔE used to identify fragments. Detected β and γ radiation. Measured half-life.
Q-value: Note: Current evaluation has used the following Q record
Q-value: Δ(S(p))=1030, Δ(Q(α))=980 (2009AuZZ,2003Au03)
Q-value: S(2n)=10010 900, s(2p)=33150 1160 (syst), Q(β-n)=7210 910 (2009AuZZ,2003Au03)
