100Pd has four proton holes in the g9/2 and four neutrons in the d5/2 orbitals around the N= Z = 50 shell closures and is therefore a suitable candidate for studying single particle effects in the nuclear wave function. The α transfer from a carbon target to an energetic beam of 96Ru close to the Coulomb barrier has been used to populate the 21+ state in radioactive 100Pd via the reaction 12C(96Ru, 8Be)100Pd. 96Ru beams of 343 MeV were provided by the Yale WNSL tandem accelerator. The two α particles from the breakup of 8Be as well as the carbon ions which Coulomb excited the Ru projectiles were detected in a Si detector in coincidence with gamma rays recorded in four Ge Clover detectors. Angular correlations and precessions have been measured via the transient field technique. Preliminary data yield the first measurement of the g factors of the 21+ state in 100Pd and of the 41+ state in 96Ru.
