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