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 T_1/2 comment for g.s. of ⁶⁴Zn in Adopted Levels for ⁶⁴Zn

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

J^π(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.
