Reduced transition probabilities and energies of high-spin states inDy162

Multiple Coulomb excitation and Doppler-broadened lineshape analyses have been applied to the nucleus ${}_{}{}^{162}{}_{}{}^{}\mathrm{Dy}$, 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 $B\left(E2\mathrm{}\right)\mathrm{}$ 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.
