Confirming band assignments in 167 ytterbium with gamma-gamma-electron triple-coincidence spectroscopy

. Multipolarity measurements are presented for transitions in the deformed odd-mass nucleus 167 Yb in support of tentative spin assignments and level interpretations based upon the cranked-Nilsson model. Internal-conversion coefficients were measured with the SAGE (Silicon And GErmanium) spectrometer confirming several E 2 transition assignments. The array of high-purity germanium detectors enabled the recording of high-multiplicity events from which γγγ and γγ e^- data sets were extracted and the technique of high-fold γ -ray gating was demonstrated to cleanly isolate transitions of interest.
