E(level): Deduced by evaluators from a least-squares fit to Eγ data.
Jπ(level): Spin and parity assignments to levels from 208Pb(14C,3nγ) are based on band structure, γ-ray multipolarities inferred from conversion electron data (2000Ri12,1987Co36), DCO ratios (1992Wi02,2017He15), and γ(θ) data in 1987Co36

1952Me13: 219Ra identified in α decay chain: 227U|)223Th|)219Rn at the 184-inch Berkeley cyclotron, where 227U was produced in bombardment of thorium nitrate with helium beam. Short half-life was deduced for the decay of 219Rn from α measurements. Later measurements at Berkeley by 1970Va13 measured the half-life more precisely
Levels: The high-spin level scheme was first proposed by 1987Co36 with the discovery of a ground-state band up to 51/2, later modified and extended by 1992Wi02, 1992Li09, 2000Ri12 and 2017He15. See also 1993Sh43 and 2001Sh14 for analysis of spectroscopic data from in-beam γ-ray and α-decay experiments. The ground state band and two side bands have been proposed, with all the three bands containing states of both parities connected by E1 γ transitions. The ground-state band has been interpreted in terms of weak coupling of a g9/2 neutron to a soft quadrupole core of 218Ra. It has K=1/2 and an expected large decoupling constant, which gives rise to Jπ=7/2+ ground state. The interpretation of the level scheme with three alternating parity bands having different K values is consistent with average B(E1)/B(E2) branching ratios deduced by 1992Wi02 and 1987Co36
