71GA c 1970Zo01: {+71}Zn source was produced by {+70}Zn(n,|g) with
71GA2c neutrons from the MIT reactor on an enriched {+70}Zn target. Measured
71GA3c E|g, I|g, |g|g-coin with NaI and Ge(Li) detectors. Deduced levels,
71GA4c J, |p, |b-decay branching ratios, log {Ift}. Comparisons with available
71GA5c data and theoretical calculations.
71GA c 1961Th04: measured E|g, I|g, |g|g, |b|g coin, T{-1/2},
71GA2c |b{+-} spectrum and |b-|g coincidences; Fermi-Kurie analysis
71GA c Other measurements:
71GA c E|g, I|g data: 1967Li01, 1955Le03
71GA c |b|g, |g|g coin: 1955Le03
71GA c T{-1/2} of {+71}Zn g.s. decay: 1962Ma24, 1958Le26, 1955Le03.
71GA c The decay scheme is from 1970Zo01, and considered as incomplete by
71GA2c the evaluators due to a large gap between Q-value and the highest
71GA3c observed excited states.
71GA cB IB,LOGFT$|b{+-} feedings from intensity balance of |g rays. Values are
71GA2cB only approximate, with no uncertainty estimate given for I|g
71GA3cB normalization due to incomplete decay scheme.

71GA2cN from decay curves, 1970Zo01 determined that 512|g is emitted in 32% of
71GA3cN the 2.45-min {+71}Zn |b{+-} activity. No uncertainty was given by
71GA4cN 1970Zo01. This value is disagrees with the earlier less complete
71GA5cN data of 1961Th04 which give I|g(512|g)=13%.
