List of levels for 173YB

Author: V. S. Shirley | Citation: Nucl. Data Sheets 75,377 (1995) | Cutoff date: 1-Oct-1993

Levels: See 1985Li06, 1987Mu09, 1987Pf01, 1991Ji06, 1991Ki14, 1991Ma48, 1992Ji06, 1992Ki29, and 1992Ku21 for recent hfs and isotope-shift data.

Gammas: All γ-ray properties are from ¹⁷³Lu ε decay except where noted.

Q-value: Note: Current evaluation has used the following Q record -670.8 176367.6 57465 6945.8 15 1993Au05

E(level): Recommended values from 1977Ta13, based on E(level) in ¹⁷²Yb(d,p), ¹⁷³Yb(d,d’), and ¹⁷⁴Yb(d,t), except where noted.

J^π(level): From consistency of level energies, angular distributions, spectroscopic factors, and relative and absolute cross sections for (d,p) and (d,t) with systematic properties of odd-mass Yb nuclei, except where noted.

T_1/2(level): Doppler-shift recoil-distance in Coulomb excitation (1989Os04), except where noted.

I(γ): Relative photon branching from each level. Upper limits are given for photon branchings affected by multiple placement.
