The structure of ${}_{}{}^{99}{}_{}{}^{}\mathrm{Pd}$ has been investigated via the ${}_{}{}^{96}{}_{}{}^{}\mathrm{Ru}$(α,n) and ${}_{}{}^{96}{}_{}{}^{}\mathrm{Ru}$${(}^6$Li,p2n) reactions in an attempt to populate low- and high-spin levels of this nucleus. Excitation functions and angular distributions of deexcitation γ rays have been measured to determine the spins of the levels deduced in γ-γ coincidence measurements carried out at 18 MeV (α particles) and 38 MeV ${(}^6$Li particles), respectively. Several new excited levels are found in the present measurements and the results show that the level structure of ${}_{}{}^{99}{}_{}{}^{}\mathrm{Pd}$ bears a strong resemblance to that of the isotone ${}_{}{}^{97}{}_{}{}^{}\mathrm{Ru}$. It appears also that ${}_{}{}^{99}{}_{}{}^{}\mathrm{Pd}$ may fit nicely into the systematics evinced in the heavier odd-A Pd nuclei.
