INTERNAL CONVERSION ELECTRONS FOLLOWING COULOMB EXCITATION OF HIGHLY DEFORMED ODD-A NUCLEI

Journal Article · · Physical Review (U.S.) Superseded in part by Phys. Rev. A, Phys. Rev. B: Solid State, Phys. Rev. C, and Phys. Rev. D

The internal conversion electrons emitted following Coulomb excitation of Eu/sup 153/, Dy/sup 161/, Dy/sup 163/, Ho/sup 165/, Tm/sup Lu/sup 175/, and Ta/ sup 181 were measured. The relative intensities of the decay transitions from the first two rotational states of these isotopes were compared with the predictions of the rotational model of Bohr and Mottelson. In general, there was good agreement betwen the experiment and theory. However, the results for the Dy isotopes indicated some disagreement which was outside the experimental unceatainty. For Eu/sup 153/, Dy/sup 163/, and Lu/sup 175/ transitions involving intrinsic states were observed in addition to the rotational transitions. The reduced E2 transition probabilities for these intrinsic transitions were appreciably larger than single-panticle estimates. The first rotational state in Lu/sup 176/ was observed with a natural Lu target. The data indicated that this transition was predominantly Ml. (auth)
