The ground-state band of the neutron-rich transuranium nucleus
Cm was established up to spin 12 by in-beam
-ray spectroscopy using the two-neutron-transfer reaction with a
Cm target and a 162 MeV
O beam. Deexcitation
rays in
Cm were identified by selecting the kinetic energies of
O particles with Si
-
detectors. The moment of inertia of
Cm
is considerably smaller than that of
Cm
, which supports the existence of the deformed subshell closure at
in Cm isotopes.
