Q(β-)=-4120 keV 90S(n)= 5980 keV 60S(p)= 3680 keV 80Q(α)= 9510 keV 60
Reference: 2021WA16

References:
  A  223U α decay (59 μs)  B  198Pt(26Mg,5nγ)

General Comments:

1973Ha32: 219Th activity was produced by 206Pb(16O,3n), E=80-90 MeV. Isotopic assignment was based on its genetic relationship to 215Ra, and also on excitation functions. Measured half-life of decay of 219Th

Theoretical calculations: 31 primary references in the NSR database (www.nndc.bnl.gov/nsr), six related to structure calculations, and 25 to radioactivity

Q-value: S(2n)=13890 60, S(2p)=6000 60, Q(εp)=530 60 (2021Wa16)

E(level): From least-squares fit to Eγ data, assuming 0.3 keV uncertainty for each γ ray

Jπ(level): As assigned in 2009Re09 based on quadrupole-octupole, parity-doublet band structures; parentheses added by evaluators due to lack of detailed information about multipolarity assignments

M(γ): From γγ(lin pol) and/or from intensity balance in 198Pt(26Mg,5nγ)
