Internal Conversion Electrons Following Coulomb Excitation of Highly Deformed Nuclei

Abstract

A study of internal conversion electrons following Coulomb excitation by alpha particles of a number of nuclei in the rare earth region has been made. In four cases, ${\mathrm{Eu}}^{153}$, ${\mathrm{Ho}}^{165}$, ${\mathrm{Lu}}^{175}$, and ${\mathrm{Ta}}^{181}$, it was possible to obtain sufficient experimental data to make a fairly complete comparison with the predictions of the simple rotational model of Bohr and Mottelson. Within the large experimental uncertainties the data were consistent with the theory.
