E(level): From least-squares fit to Eγ data for levels populated in γ-ray studies. In cases, where ΔEγ is not stated, 0.3 keV is assumed when Eγ is stated to nearest tenth of a keV, and 1 keV when Eγ is stated to nearest keV. Energy uncertainties of 11 γ rays were doubled to obtain an acceptable reduced χ2=1.9 as compared to critical χ2=1.4. Without this adjustment reduced χ2 was 3.7. For levels populated in particle transfer reactions only, weighted averages have been taken of all the available values. In case of unresolved doublets in particle transfer reactions, quoted energy value not included in obtaining average level energy.
Jπ(level): When assigned from L(p,d), the following shell-model orbitals are assumed (by 1983Ga07) for the transferred nucleon: p3/2 for L(n)=1; d3/2 (below≈1.5 MeV excitation) and d5/2 (above≈1.5 MeV excitation) for L(n)=2; f5/2 for L(n)=3; g7/2 for L(n)=4; h11/2 for L(n)=5. In in-beam γ-ray study when no γ(θ) and/or ce data are available, it is assumed that in such reactions, levels of ascending Jπ are populated with increasing excitation energy. Absence of transitions to levels of low Jπ values also supports such a conclusion. Unless otherwise stated, L transfers are from 0+ targets
T1/2(level): Unless stated otherwise, values are derived from B(E2) values in Coul. ex., adopted branchings and mixing ratios.
E(γ): As indicated, values for γ rays from low-spin (J|<9/2) are from 149Eu and 149Pm decay data, and for higher-spins, values are from (α,nγ) when given with uncertainties, and from 148Nd(α,3nγ),150Nd(3He,4nγ), when given without uncertainties, unless otherwise noted.
I(γ): Below 953 excitation energy, Iγ data are mainly from 149Pm β- decay or 149Eu ε decay or weighted average when values from these two datasets have comparable uncertainties; above this energy, values available from (α,nγ) and 148Nd(α,3nγ), 150Nd(3He,4nγ) are considered, unless otherwise noted.
M(γ): From ce studies in 149Pm β-, 149Eu ε and in-beam γ-ray. Above 636 keV level, the assignment is from ce and/or γ(θ) and γ(lin pol) data in in-beam γ-ray studies
