General Comments:

2000Mu10: 238U(p,F) with E(p)=30 MeV. Fragments extracted with Louvain ion-guide laser-ion source (LIGLIS) and separated with LISOL mass separator. Measured Eγ, Iγ, Eβ, γ(t), βγ- and γγ-coincidences with two HPGe detectors and three ΔE plastic detectors.

1999Le67,1999So20: 58Ni(86Kr,X) with E(86Kr)=60.4 MeV/nucleon. Fragments separated by the LISE3 spectrometer and identified by ΔE, total E and time of flight. Measured T1/2, Eβ, β(t) using segmented Si detector.

1993BeZM,1992CzZX,1992CzZy,1991Be33: Thermal induced fission of 235U or 239Pu. Fragments separated by the LOHENGRIN recoil spectrometer and identified by ΔE-E. Measured β(t), T1/2 using eight planar Si detectors.

Others: 2002Kr13, 1999GrZQ, 1994Se12, and 1985Gu14.

Q-value: Note: Current evaluation has used the following Q record 11550 130 4.66e+3131.351e+444 -11350 130 2011AuZZ

Q-value: S(2n)=11650 130; S(2p)=29740 130; Q(β-n)=3760 130 (2011AuZZ).

Jπ(level): The proton configuration in Co is πf7/2-1. 69Ni is observed by 1999Mu17 to have a β decaying isomer with Jπ=(9/2+) and proposed configuration of νg9/2+1. Thus, the ground state is suggested to be the πf7/2-1 νg9/2+1 configuration and the lowest state of the multiplet is 7- (2000Mu10).
