Deformation-driving properties of the. nu. i/sub 13/2/(660)(1/2/sup +/ intruder orbital for Aapprox. 130 nuclei

· Phys. Rev. Lett.; (United States)
Several rotational-band structures have recently been observed in mass Aapprox. =130 nuclei, built on multiquasiparticle states of enhanced quadrupole deformation, the so-called superdeformed states (..beta..approx. =0.4). In /sup 137/Sm, a decoupled band built on the ..nu..i/sub 13/2/(660)(1/2/sup +/ single-quasineutron orbital, intruding from two oscillator shells above with a predicted ..beta..approx. =0.35, was observed to low spin and excitation energy. The role of this ..beta..-driving ..nu..i/sub 13/2/ orbital, which showed a 50% enhanced moment of inertia, is discussed in terms of the superdeformation in this mass region.
