The ground-state rotational band of the neutron-deficient californium (
Z
=
98
) isotope
244
Cf
was identified for the first time and measured up to a tentative spin and parity of
I
π
=
20
+
. The observation of the rotational band indicates that the nucleus is deformed. The kinematic and dynamic moments of inertia were deduced from the measured
γ
-ray transition energies. The behavior of the dynamic moment of inertia revealed an up-bend due to a possible alignment of coupled nucleons in high-
j
orbitals starting at a rotational frequency of about
ℏ
ω
=
0.20
MeV
. The results were compared with the systematic behavior of the even-even
N
=

isotones as well as with available theoretical calculations that have been performed for nuclei in the region.
