Abstract

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.
