O205600100016 The Si was in the form of approx. 500 mg of 99.99% pureO205600100017 powder wrapped in thin gold foil. Each of the nitrogen O205600100018 targets consisted of approx. 5 g of high purity O205600100019 vanadium nitride powder that had been compressed into O205600100020 disks 20 mm in diameter and 0.5 mm in thickness. O205600100021 For Be-7 production-target stack consisting of 25-mm O205600100022 diameter disks of Al 3*21.2 mg/cm**2, Si 54.1 mg/cm**2,O205600100023 Al 21.2 mg/cm**2, Mg 79.4 mg/cm**2 and Al 21.2 mg/cm**2O205600100024 was used.
