64Zn can decay by double β decay to 64Ni. Many measurements have been reported dealing with search for β transition to 64Ni g.s.. No definitive decay has been observed, upper limits on 64Zn half-life have been established. The latest reports are 2020Az05, 2011Be39, 2010Be41, 2009Be27, 2009Da16, 2008Be02, 2007Bl15, 2006Wi12, 2006Zu02. For details, see T1/2 comment for g.s. of 64Zn in Adopted Levels for 64Zn

Q-value: S(2n)=16495.23 21, S(2p)=22798.9 28 (2021Wa16)

E(level): From a least-squares fit to γ-ray energies with uncertainties for levels connected with those γ transitions and from reaction data for others, unless otherwise noted. Above ≈4 MeV, due to high level density and limited resolution the correspondence of levels from different reactions is somewhat ambiguous

Jπ(level): Above 3.5 MeV, due to high level density L-transfer values available from only one reaction such as (t,α) or (d,3He) are considered tentative for Jπ assignments.
