List of levels for 245CM

Authors: E. Browne, J. K. Tuli | Citation: Nucl. Data Sheets 112, 447 (2011) | Cutoff date: 1-Jun-2010

Other reactions:

²⁴⁴Cm(n,γ): Calculated cross-sections (2009MaZK).

²⁴⁴Cm(n,F): Measured Eγ, Iγ. Deduced cross-sections (2008BrZW,2008JuZZ).

Analyzed neutron-capture and fission cross sections (2008Pa14,2005Oh05)

Measured neutron-capture and fission cross-sections (2007Ko28).

Levels: See 1971Br27, 1971Ga20, 1974Mo18 and 1976Ch22 for theoretical calculations of quasiparticle energies and collective states.

Q-value: Note: Current evaluation has used the following Q record

E(level): Deduced by evaluators from least-squares fit to γ-ray energies, unless otherwise specified.

J^π(level): Assignments from (d,p), (d,t) data are based on L-transfer values deduced from cross sections measured at 90|’ and 140|’, and on comparison of experimental cross sections with calculated "signatures ". Nilsson orbital and band assignments to some levels above 900 keV are tentatively proposed in 1971Br27 from (d,p) and (d,t) reaction data. For the suggested assignments, see (d,p), (d,t) reactions.

E(γ): From ²⁴⁹Cf α decay, ²⁴⁵Bk ε decay and ²⁴⁵Am β^- decay.

I(γ): Relative intensity from each level.

M(γ): From ²⁴⁹Cf α decay and ²⁴⁵Bk ε decay
