Over the past several years measurements have been made of the fragmentation of Silicon and Oxygen at energies less than 360 MeV/nucleon on Carbon and polyethylene targets. The apparatus to identify fragment isotopes consisted of a stack of 36 solid detectors, beam geometry and characterization versus laboratory production angle was measured by moving the apparatus relative to the beam direction. Single particle inclusive cross sections appropriate for astrophysical applications have been determined by integrating over the full solid angle. Cross section results for both Carbon and Hydrogen targets (using CH{sub 2}-C subtraction) will be reported and compared to available data and semi-empirical calculations. The implications for cosmic ray propagation in the interstellar medium will be discussed.
