Rotational bands have been identified up to high spins ($\ensuremath{\approx}$$28\ensuremath{\hbar}$) in the odd-$A$ nuclei $^{247,249}\mathrm{Cm}$ and $^{249}\mathrm{Cf}$ through inelastic excitation and transfer reactions around the $Z=100$ region where stability results from shell effects. The [620]1/2 Nilsson configuration in $^{249}\mathrm{Cm}$ is the highest-lying neutron orbital, from above the $N=164$ spherical subshell gap, for which high-spin rotational behavior has been established. The data allow for an unambiguous experimental assignment of configurations to the observed bands, unusual for odd-$A$ nuclei near $Z=100$. The high-spin properties are described in terms of Woods-Saxon cranking calculations.
