General Comments:

Data are from 162Lu ε decay (primarily 2004Mc01) and in-beam studies, namely the level scheme of 1987Mo21 and the γ data of 1987Mo21 and 1980BeYG.

Levels: The several (HI,xnγ) studies in some cases give different sequences of γ’s, so the level energies are not well known, and in some cases different Jπ’s are assigned even where the sequences agree.

Levels: For levels with J=20-32, the average g-factor is 0.24 5 from the evaluation of 1989Ra17 and is based on the data of 1984Ma10.

Gammas: In their lifetime measurements, 1992Mc02 report only partial lifetimes (and, in some cases, reduced transition probabilities) for individual transitions, but not level lifetimes. For those levels having more than one deexciting transition, it has been necessary for the evaluator to compute the level half-life values from these reported quantities. In giving the reduced transition probabilities (in W.u.) in these cases, the evaluator has listed the "directly reported " values of 1992Mc02 rather than those computed from the listed T1/2 values. These instances are pointed out in the associated comments.

Q-value: Note: Current evaluation has used the following Q record

Jπ(level): Where no specific arguments are listed, the Jπ and band assignments are from interpretation of the in-beam γ data (1987Mo21), except as otherwise noted. These assignments are based on general considerations of the properties of rotational-band structure as well as the measured DCO ratios and γ(θ) data, supplemented in some instances with α(K)exp data. These latter data are helpful in establishing relative parity values for the two states involved in the respective γ transitions.

T1/2(level): Unless otherwise noted, the T1/2 values for the excited states are derived from the Doppler-shift recoil-distance data of 1992Mc02, measured in the 116Cd(50Ti,4n) reaction. For a further discussion of the procedures used in deriving these values, see the (HI,xnγ) data set.

E(γ): The values with listed uncertainties are those reported by 2004Mc01, from 162Lu ε decay, and by 1980BeYG, from in-beam spectroscopy. Those values for which no uncertainties are given are from in-beam spectroscopy of the 122Sn(44Ca,4nγ) reaction (1987Mo21), unless noted otherwise.

I(γ): From the 122Sn(44Ca,4nγ) reaction, with E(44Ca)=195 MeV (1987Mo21)

M(γ): From DCO ratios and γ(θ) data from the heavy-ion studies, unless noted otherwise. In distinguishing between E1/M1 and E2/M2 from these data, the authors, and the evaluator, have taken note of the existence of a well developed rotational-band structure to choose E2 over M2, when mult=Q is indicated, and generally M1, when mult=d is indicated.

    487.33    320.60E(γ): Multiply placed
M(γ): from γ(θ) in 150Sm(16O,4nγ), (1980BeYG). See the comment in the (HI,xnγ) data set.
    798.42    631.67M(γ): mult=Q from γγ(θ) in 162Lu ε decay (1983Ge08). From the observed γ decay from this level, the evaluator has concluded that the deexciting γ’s are much more reasonably assigned as E2 than M2.
    924.14    436.80M(γ): From internal conversion coefficients measured in the in-beam study of the 150Sm(16O,4nγ) reaction (1980BeYG). Usually these data are supplemented by DCO ratios and γ(θ) data from the heavy-ion studies, but we mention only the conversion data, since they can provide a distinction between E1/M1 and E2/M2 for dipole and quadrupole transitions, respectively.
   1006.20    839.40M(γ): mult=Q, from γγ(θ) in 162Lu ε decay (1983Ge08). The evaluator has regarded mult=E2 to be a more reasonable choice than the alternative, mult=M2.
