E(level): For levels deexcited by γ rays: from least-squares fit to Eγ, assigning 1 keV uncertainty to Eγ data for which uncertainties are unknown and excluding the 676γ and 362γ, both of which fit their placements particularly poorly. This results in a reduced χ² of 3.3 (cf. Critical value of 2.1), compared with 41 when all gammas are included, 26.5 if only the 676γ is omitted or 22.2 if only the 362γ is omitted. Level energies from other reactions are taken from the cross-referenced source unique to the level. Note that levels with E(level)=1195 10 from (t,p), 1217 10 from (d,p) and 1227.2 3 from (t,pγ) are probably all the same (21/2-) level. It appears then, that the energy calibrations of the three experiments are not in good agreement; this complicates cross referencing for levels above 1227 keV.
