The ground-state band of the neutron-rich transuranium nucleus 250 Cm was established up to spin 12 by in-beam γ-ray spectroscopy using the two-neutron transfer reaction with a 248 Cm target and a 162 MeV 18 O beam. Deexcitation γ rays in 250 Cm were identified by selecting the kinetic energies of 16 O particles using Si Δ E – E detectors. The moment of inertia of 250 Cm 154 is considerably smaller than that of 248 Cm 152 , which supports the existence of the deformed subshell closure at N =152 in Cm isotopes.
