E(level): From least-squares fit to Eγ data, assuming 1 keV uncertainty when not stated. For levels populated in (γ,γ’):E=1.2-4.1 MeV, 1 keV uncertainty is assumed by the evaluators

Jπ(level): From angular momentum transfer in inelastic scattering for levels between 2.6 and 3.0 MeV; angular momentum transfer in (d,p) for levels between 3.0 and 4.4 MeV, except as noted; and resonance analysis for unbound states above 16 MeV. For levels populated in (γ,γ’), Jπ is limited to 5/2,7/2,9/2 from expected dipole excitation from 7/2+ g.s. of 139La
