169LU c  Isomer identified using excitation-function data for
169LU2c  Yb(p,xn) (1965Bj01).
169LU c  The decay scheme and all data are from 1965Bj01. Sources from
169LU2c  {+170}Yb(p,2n), E(p)=13 MeV (pulsed beam); Yb metal targets
169LU3c  enriched to 85% in {+170}Yb. Measured E(ce), Ice (magnetic
169LUxc  spectrometer).
169LU cG RI        Deduced from I(|g+ce) and |a.
169LU cL J,T       From Adopted Levels, except as noted.

169LU cG M         (L1+L2)/L3 is consistent with E2 or E3. The lifetime,
169LU2cG compared to the Weisskopf estimate, corresponds to a
169LU3cG retardation of 1|*10{+9} times for E2 and about 1|*10{+3} times for
169LU4cG E3, and thus strongly favors E3 (1965Bj01).
