Abstract.
Low-lying two-quasiparticle bandhead energies for the Z = 99 odd-odd nucleus 254Es are evaluated using a simple phenomenological model with the inclusion of the residual p-n interaction. Configurations of the intrinsic levels directly fed in 254Es from the parent 258Md are discussed in the light of this model. Our analysis predicts the occurrence of ten K≤5 bandheads in 254Es with excitation energies E x≤300keV. Structures of these as yet unidentified low-lying intrinsic levels and their expected locations are discussed in the light of available experimental information.
