Additional Gamma Comments:

E(level)E(gamma)Comments
  312.5  196.2I(γ): Others: Iγ(196γ)/Iγ(312γ)=132 24 in 2012Ka36 in contradiction with 2011Wa03. The authors in 2012Ka36 stated that the 196.2γ is contaminated in their work by a 197.1 keV γ ray, produced in the 19F(n,n’) reaction, and that a correction to Iγ(196.2γ) was applied
  312.2I(γ): see the comment to the 196.2γ
