Nuclear rotation at the fission limit in ²⁵⁴Rf

NUCLEAR REACTIONS ²⁰⁶Pb(⁵⁰Ti, 2n)²⁵⁴Rf, E=244 MeV from the ATLAS-ANL facility; measured reaction products, prompt γ rays, Eγ, Iγ, Rf K_α and K_β x-rays, (²⁵⁴Rf implants)γ-coin, (implants)(fission events)γ-coin using the Gammasphere array and the Argonne gas-filled analyzer (AGFA). ²⁵⁴Rf; deduced levels, J, π, ground-state rotational band up to 14+, kinematic moment of inertia. Systematics of ground-state bands in ²⁵⁰Fm, ^252,254No, and ^254,256Rf, and comparison with particle-number conserving cranked shell model (PNC-CSM) calculations.
