Level structure ofPd106from the decay ofRhg106

The low-spin level structure of ${}_{}{}^{106}{}_{}{}^{}\mathrm{Pd}$ was studied using high-resolution large volume Ge(Li) detectors for $\gamma$-ray singles, coincidence, and angular correlation measurements. The measurements allowed the resolution of most of the discrepancies found among previous studies. In particular, the use of two Ge(Li) detectors for coincidences and angular correlations allowed unambiguous placement of previously multiply placed $\gamma$ rays and resolved discrepancies in energy level or $J^{\pi }$ assignments. The experimental level structure and $B\left(E2\mathrm{}\right)\mathrm{}$ ratios are compared with predictions of an anharmonic spherical vibrator model and a rotor-vibrator model; we find that the evidence strongly supports the latter of the two models.
