We have measured the elemental abundances of galactic cosmic-ray Zn, Ga, and Ge using the CRIS instrument on the NASA-ACE spacecraft. These ultra-heavy (Z>29) nuclei are very rare and require an instrument with a large geometrical factor, such as CRIS possesses, exposed over a long period of time to collect a significant sample. Over the 10+ years since launch in 1997 we have collected ˜250 nuclei with Z>29. Abundances for these elements measured over the energy range of ˜150 to 600 MeV/nucleon will be presented and implications for the nature of the cosmic ray source will be discussed.
