title: Elemental investigation of some Egyptian vehicle motor alloys using neutron activation analysis.
abstract: Six samples of different Egyptian motor vehicle alloys have been investigated by neutron activation analysis to estimate the concentrations of their elemental constituents, which affect their quality. A single high resolution hyper-pure germanium HPGe gamma-ray detector and a multichannel analyzer are used to collect the gamma-ray spectra. A HPGe-HPGe coincidence spectrometer was also used to confirm the identity of certain peaks. Thirteen trace elements (Sc, Cr, Fe, Co, Zn, Sn, Sb, La, Sm, Eu, Hf, Pt and Au) were observed in the spectra and their concentrations were determined. A comparative study on the element concentrations for the six samples is given.
