E(level): Level energies have been calculated by the evaluator using least-squares fit to Eγ.

Jπ(level): Many of the Jπ assignments are based upon γ(mult) and γγ(θ) analysis of 1982Ch22 in β- decay. The authors have assumed that the transitions from 1+ levels at 756, 991 and 1086 to levels <500 are predominantly E1. Supporting many Jπ assingments, calculations of levels configurations in terms of shell-model and Nilsson orbitals can be seen in 1982Ch22.
