  High-$K$ isomeric states in even-even and odd-mass nuclei are described
within a mean-field framework with full blocking and using the finite range
Gogny force. Theoretical calculations of low energy spectra of several nuclei
across the nuclear chart are compared with equal filling approximation results
and experimental data. Despite the global character of the employed
interactions, a good agreement between the different many-body methods and
experimental data is found.
