Collectivity of the superdeformed bands in /sup 152/Dy

Journal Article · · Phys. Rev. Lett.; (United States)
The lifetimes of the ..gamma.. rays in the collective rotational bands observed in the ..gamma..-ray continuum at very high spin /sup 152/Dy are shown to be less than 100 fs for energies above 0.90 +- 0.05 MeV. The corresponding B(E2) values are very enhanced and provide definite evidence that the rotational bands are associated with a superdeformed prolate structure in /sup 152/Dy.
