Additional Gamma Comments:

E(level)E(gamma)Comments
  3168.5   222.1M(γ): stretched d γ from asymmetry ratio, (E1) based on theoretical arguments implying unique parity orbitals νi13/2 and πh11/2 and systematics of even-even nuclei in this mass region having a similar decay pattern: 11- level at about 3 MeV exitation energy decaying to 10+ level of the g.s. band by E1 transition. For example for 156Er, 158Er, 158Yb, 158Hf, 160Hf, 162W and 164W nuclei having this pattern no 11+ level was found, except for 156Er where this level is placed at more than 600 keV above 11- level
