Reduced transition probabilities and energies of high-spin states in 162Dy

Multiple Coulomb excitation and Doppler-broadened line-shape analyses have been applied to the nucleus 162Dy, allowing ground-band energies through the 18+, lifetimes through the 14+, and reduced transition probabilities through the 18+ state to be determined. Energy levels show smooth departure from the rotational model with no backbending, while the B (E2) values are consistent with the rotational model through spin 18. Comparison is made to similar results for high spins in other good rotors. The results strengthen our conclusions reached in previous papers: The compression of energy levels observed at high spins in good rotors is largely due to pairing changes, which have only a small effect on transition probabilities
