E(level): From least-squares fit to Eγ.

Jπ(level): From (29Si,3nγ), based on γ multipolarities, γ branching, and band structure deduced from band crossing frequencies, alignments and alignment gains, except as noted.

M(γ): Based on γ(θ) in (29Si,3nγ), except as noted, assigning Δπ=(no) to intraband transitions.

Additional Gamma Comments:

E(level)E(gamma)Comments
   286.70   286.70M(γ): 287γ and 463γ are Q from γ(θ); in (29Si,3nγ) intensity balance at 287 level precludes M2 for either or both of these transitions.
   749.90   463.20M(γ): 287γ and 463γ are Q from γ(θ); in (29Si,3nγ) intensity balance at 287 level precludes M2 for either or both of these transitions.
  2841.1   295.9M(γ): γ(θ) consistent with Q, ΔJ=2 or D+Q, ΔJ=0; intensity balance arguments in (29Si,3nγ) favor M1.
  2958.8   117.7M(γ): γ(θ) suggests dipole transition, but intensity balance suggests E2 in (29Si,3nγ) (1988Dr06); level scheme requires the latter.
