E(level): For the levels above the 9+ level, the values are from a least-squares fit to the γ energies as given in the heavy-ion data set.
Jπ(level): Above the 9+ level, the Jπ assignments are from the heavy-ion studies of 2002Fo07 and are based on the γ multipolarities and the expected level sequences. No specific arguments are given for the Jπ values of the levels above this one.
M(γ): From conversion-electron data in the respective studies.
