O050100100013 admixtures: Na <50 ppm, Al < ppm, (SI) Less 50 ppm), O050100100014 2. 5.29-7.27 mg/cm**2 Al purity >99.9%, O050100100015 admixtures: Na+Mg < 500 ppm, Si < 500 ppm.

O050100100019 The Mg and SiO(2) targets were irradiated individually,O050100100020 The Al targets were nearly all run as portions of O050100100021 target stacks involving from 45 to 1000 mg/cm**2 of O050100100022 other (much higher Z) materials.
