Single-particle state assignments in {sup 251}Cf and {sup 249}Cm at {approx}1 MeV excitation have been deduced from cross sections previously measured for the {sup 250}Cf(d,p){sup 251}Cf and {sup 248}Cm({sup 4}He,{sup 3}He){sup 249}Cm reactions. The assignments are supported by observed cross-section signatures and intraband level spacings. The observed energies of these single-particle states, after pairing effects are removed, are in good agreement with values calculated using a Woods-Saxon single-particle potential. Neutron level diagrams, showing level spacings as a function of {nu}{sub 2},{nu}{sub 4}, and {nu}{sub 6}, are extended to include neutron orbitals above N=164.
