Extreme prolate deformation in light strontium isotopes
- 1. Department of Physics, Schuster Laboratory, University of Manchester, Manchester M13 9PL, England
Description
Multiple-particle, γ-ray coincidence techniques have been used to study neutron-deficient isotopes near N = Z = 40. Results are presented for 77-80Sr. Levels in 78Sr were seen to J = 10 with E(2+) = 278 keV and T/sub 1/2/ = 155 +- 19 ps. The results suggest that this region contains some of the most deformed nuclei known, with quadrupole deformations epsilon2roughly-equal0.4. These data resolve conflicting theoretical predictions of nuclear shapes and emphasize the important contribution of hexadecapole deformation in determining the most stable shape
