General Comments:

1982No08: identification and production of 148Er isotope

Levels: In the table below, observed levels in 148Er are classified in terms of spherical shell-model configurations while comparing with the known states in n=80 isotones and other neighboring nuclides (146Dy,144Gd,148Dy and 150Er). The valence orbitals are: h11/2, s1/2, d3/2, g7/2 2-neutron holes; 2-4 proton orbitals (mainly h11/2) outside the 146Gd core. Six-qp configurations are expected above 7 MeV, but 2001Ro15 did not identify specific levels for these configurations due to high level density

Q-value: S(2n)=23300 12, S(2p)=3502 12, Q(εp)=5428 14 (2021Wa16)

E(level): From least-squares fit to Eγ data

Jπ(level): All assignments are from 92Mo(58Ni,2pγ), based on γ-anisotropy data, decay pattern, yrast type of population in heavy-ion studies, γ-sequence assignments. The parentheses are added by the evaluators

M(γ): From γ-asymmetry data in 92Mo(58Ni,2pγ)
