Abstract  

A polycrystalline silicon specimen, cut off from an ingot directionally solidified from upgraded metallurgical grade silicon /UMG-Si/ has been examined using a 1.45 MeV deuteron microbeam. The superficial distributions of carbon and oxygen were determined by direct observation of nuclear reactions. Several carbon concentration ranges were identified. Oxygen is always strongly correlated with carbon, but the nature of this correlation has to be specified. The presence of iron was shown inside areas with strong carbon precipitation.
