  We have performed self-consistent Skyrme Hartree-Fock-Bogolyubov calculations
for nuclei close to $^{254}$No. Self-consistent deformations, including
$\beta_{2,4,6,8}$ as functions of the rotational frequency, were determined for
even-even nuclei $^{246,248,250}$Fm, $^{252,254}$No, and $^{256}$Rf. The
quasiparticle spectra for N=151 isotones and Z=99 isotopes were calculated and
compared with experimental data and the results of Woods-Saxon calculations. We
found that our calculations give high-order deformations similar to those
obtained for the Woods-Saxon potential, and that the experimental quasiparticle
energies are reasonably well reproduced.
