  An extension of the Barcelona Catania Paris Madrid (BCPM) energy density
functional is proposed to deal with odd-mass systems as well as
multiquasiparticle excitations. The extension is based on the assumption that
the equal filling approximation (EFA) is a valid alternative to the traditional
full blocking procedure of the Hartree-Fock-Bogoliubov method. The assumption
is supported by the excellent agreement between full blocking and EFA
calculations obtained with different parametrizations of the Gogny interaction.
The EFA augmented BCPM functional is used to compute low energy excitation
spectra of selected nuclei in different regions of the nuclear chart, and
high-$K$ isomers in $^{178}$Hf. We show that BCPM predictions are in good
agreement with Gogny D1M results and experimental data.
