Abstract: (APS)

Multiple-particle, γ-ray coincidence techniques have been used to study neutron-deficient isotopes near N=Z=40. Results are presented for Sr77−80. Levels in Sr78 were seen to J=10 with E(2+)=278 keV and T12=155±19 ps. The results suggest that this region contains some of the most deformed nuclei known, with quadrupole deformations ε2≈0.4. These data resolve conflicting theoretical predictions of nuclear shapes and emphasize the important contribution of hexadecapole deformation in determining the most stable shape.
