E(level): From a least-squares fit to Eγ, unless otherwise specified

Jπ(level): From deduced transition multipolarities (204Hg(t,pγ)) using γ(θ) in 1982Be38 and 1984Ma43, and L values in 1978Fl08, unless otherwise specified

Additional Gamma Comments:

E(level)E(gamma)Comments
  1068.20  1068.2M(γ): From A2=+0.22 2 in 204Hg(t,pγ) (1982Be38). The positive sign argues against a ΔJ=1 transition; Mult.=M2 is excluded from systematics of first excited states in neighboring even-even nuclei
  2102.4  1034.2M(γ): A2=0.38 5 in in 204Hg(t,pγ) (1982Be38). The measured ratio of A2(1068γ)/A2(1034γ)=0.58 9 is consistent with a J=5 to 2 transition for which A2(2 to 0)/A2(5 to 2)=0.6 can be expected, whereas A2(2 to 0)/A2(4 to 2)=1.0 could be expected if 1034γ were E2 (1982Be38)
