contents Following our study of possible $K$-isomers in odd-even Md-Rg nuclei, here we continue with searching for three-quasiparticle 1$ν$2$π$ and 3$ν$ isomer candidates in even-odd Fm - Cn nuclei. We use the same approach to calculate energies of different nuclear configurations using a microscopic-macroscopic model with the Woods-Saxon potential. We used two versions of pairing: quasi-particle BCS method and particle number projection formalism. The optimal deformations for both ground states and high-$K$ configurations are determined through a four-dimensional energy minimization process. We point out the most promising candidates for high-$K$ isomers and compare them, where possible, with existing experimental data.
