A rotational band with a constant moment of inertia I(2)=58ℏ2 MeV-1 has been observed in 152Dy extending from spin 18+ to 40+. The band coexists with the known oblate yrast states although it is up to 1.5 MeV higher in excitation energy. It carries 4% of the decay strength and it is proposed to be a four-quasiparticle aligned structure. It is conjectured that the superdeformed states at the highest spins may decay via this band rather than via the yrast oblate states.
