ResumoA collective model which incorporates vibrations and rotations of a permanently deformed nucleus is applied to $^{102}\mathrm{Pd}$, $^{104}\mathrm{Pd}$, $^{106}\mathrm{Pd}$, $^{108}\mathrm{Pd}$, $^{110}\mathrm{Pd}$, $^{112}\mathrm{Pd}$, and $^{114}\mathrm{Pd}$. Theoretical energy levels are compared with those from experiment and remarkably good agreement is found. The model wave functions are further tested via $B(E2)$ ratios and agreement with experiment is very good. An unidentified extra degree of freedom is treated essentially by ansatz but a discussion of the possible origin of that degree of freedom is given. Trends in the model parameters are shown and the conclusion drawn that to a good approximation the states of these even-mass Pd isotopes are well described as those of collective rotations and vibrations.NUCLEAR STRUCTURE $^{102,\phantom{\rule{0ex}{0ex}}104,\phantom{\rule{0ex}{0ex}}106,\phantom{\rule{0ex}{0ex}}108,\phantom{\rule{0ex}{0ex}}110,\phantom{\rule{0ex}{0ex}}112,\phantom{\rule{0ex}{0ex}}114}\mathrm{Pd}$.
