167ER cE $|e feedings are from intensity imbalance at each
167ER2cE level; no feeding to g.s. is expected, because |DJ=3.
167ER cG $Measured L-shell Auger electron intensities (1979ArZU):
167ER2cG 0.45% {I5} for KL1L1, 0.67% {I7} for KL1L2, 0.09% {I4} for KL2L2,
167ER3cG 0.57% {I6} for KL1L3, 1.13% {I11} for KL2L3, 0.50% {I5} for KL3L3,
167ER4cG 3.4% {I2} for summed KLL, and 150% {I30} for summed LXY. See also

167ER cG $I(Er K|a| x ray)=310, relative to I|g=10.0 for 531.5|g
167ER2cG (1960Na14) (after correction for absorption and assuming |w{-K}=0.949),
167ER3cG compared with I(Er K|a| x ray)=466 from decay scheme.
167ER cG E(d),RI(e)$From 1968Fu09
167ER cG E(f)$From the Adopted Gammas
167ER cG E(a)$Rounded-off value from the Adopted Gammas. Transition is
167ER2cG expected, but has not been observed in {+167}Tm |e decay.
167ER cG RI(a)$Negligible; if it is assumed that there is no |e branch, the only
167ER2cG feeding into the 281.6 level is from 250.2|g (I|g=0.014).
