E(level): Relative to 222 keV for the 15/2-,9/2[734] state (2007Ma82). Evaluators have adjusted to the same scale the energies of levels populated in (d,p).

Jπ(level): Spin and Nilsson state assignments to levels populated in the (d,p) reaction are based on rotational structure and on cross sections measured at θ=90|’, 120|’, and 150|’; and on comparison of experimental cross sections with theoretical values. Assignments from 244Pu(18O,17O γ) are based on rotational structure also, and on γ-ray multipolarities.
