68ZN c 1975Ti01: {+68}Cu activity produced by {+68}Zn(n,p), E(n)=14.9 MeV.
68ZN2c Measured E|g, I|g, and T{-1/2} using Ge(Li) detector.
68ZN c 1972Sw01: {+68}Cu activity produced by {+68}Zn(n,p), E(n)=14.7 MeV.
68ZN2c Measured E|g, I|g, E|b{+-}, I|b{+-}, T{-1/2}, |g|g and |b|g coin
68ZN3c using Ge(Li) and NaI(Tl) detectors and a plastic scintillator.
68ZN c Data are taken mainly from 1972Sw01 and 1975Ti01.
68ZN c Others: 2002Ko31, 1971Si19, 1969Wa22, 1969Va16, 1964Ba13, 1960Yt03.
68ZN c The decay scheme given here is based on the equilibrium decay of the
68ZN2c 3.75-min {+68}Cu isomer which proceeds 86% via IT decay and
68ZN3c subsequent decay of the 30.9-s g.s. to {+68}Zn. This branching
68ZN4c fraction includes a correction for the different T{-1/2} of the two
68ZN5c branches. Included here are only those |g's which decay with a
68ZN6c composite 30.9-s and 3.75-min half-life and their associated levels.
68ZN cL E$From a least-squares fit to the E|g's by evaluator.
68ZN cL J,T$From the Adopted Levels.
68ZN cG E$From 1975Ti01. Transition with E|g=570.7 reported by 1972Sw01 is
68ZN2cG not confirmed by 1975Ti01 and is not adopted here.
68ZN cG RI$Weighted average of 1975Ti01 and 1972Sw01, relative to
68ZN2cG I|g(525.9|g)=100 in {+68}Cu IT decay. Taken or calculated from I|g's
68ZN3cG observed in the equilibrium decay: {+68}Cu |b{+-} decay (30.9 s +
68ZN4cG 3.75 min) using branching fraction. Full separation of I|g's
68ZN5cG associated with 30.9 s and 3.75 min |b{+-} decays was not possible
68ZN6cG with the data available. I|g's are listed here for only those |g's
68ZN7cG which decay with a composite 30.9-s and 3.75-min half-life.
68ZN cG M,MR$From the Adopted Gammas.
68ZN cG RI(a)$Intensity deduced by evaluator based on equilibrium decay
68ZN2cG intensities for {+68}Cu |b{+-} decay (30.9 s + 3.75 min), branching
68ZN3cG fraction and assumptions on feeding.
68ZN cB E$Experimentally measured values from |b|g coincidences are included
68ZN2cB in the comments.
68ZN cB IB$From I|g imbalances in {+68}Cu |b{+-} decay (30.9 s + 3.75 min) in
68ZN2cB equilibrium. Branches to low-spin states are assumed to be from the
68ZN3cB 30.9-s parent state.
68ZN cB IB(B)$Others: 31.4% {I41} from |g intensities and 28.0% {I42} from
68ZN2cB comparison with |b{+-} in coincidence with 1077|g (1972Sw01); 37%
68ZN3cB (1971Si19).

68ZN2cN I|g(525.9|g)=100, I|g's give 114.5 {I18} decays which then undergo
68ZN3cN |b{+-} decay (30.9 s).
