Abstract

Using the two-parameter expression for rotational spectra, E(I)=a[ √1+bI(I+1) -1], derived from the Bohr Hamiltonian, the spins of 22 superdeformed bands observed in the A∼190 region were determined. The calculated transition energies depend sensitively on the prescribed spins. The agreement between the calculated and observed transition energies is incredibly well when a correct spin assignment is made. The kinematic and dynamic moments of inertia were extracted from the observed transition energies and their variation with rotational frequency was investigated.
