Levels in Pd99 populated by the Ru96(α,n) and (6Li,p2n) reactions

The structure of Pd99 has been investigated via the Ru96(α,n) and Ru96(6Li,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 (6Li particles), respectively. Several new excited levels are found in the present measurements and the results show that the level structure of Pd99 bears a strong resemblance to that of the isotone Ru97. It appears also that Pd99 may fit nicely into the systematics evinced in the heavier odd-A Pd nuclei.
