  A  85Zr IT decay (10.9 S)  B  85Nb ε decay (20.5 S)
  C  85Nb ε decay (3.3 S):?  D  56Fe(35Cl,APNG)

General Comments:

85Zr produced and identified (1963Bu06) in bombardment of Y and Sr by 230 MeV protons and measuring half-life by β and γ activity. Later decay studies: 1971Yu02, 1971Do01, 1972Tu07, 1976Ia01, 1977Ia01, 1982De36, 1992Bu10, 2005Ka39

Many additional high-spin levels and gamma rays are proposed in 60Ni(28Si,2pnγ) reaction (2003WeZY). Due to the tentative nature of the results reported in this secondary reference, these levels and gamma rays are not adopted here. See 60Ni(28Si,2pnγ) dataset for this information.

Mass measurements: 2006Ka48, 2012Ka13 (Penning-trap method)

Q-value: Q(εp)=187 7, S(2n)=23406 9, S(2p)=10954 9 (2012Wa38)
