Abstract
Thin Layer Activation (TLA) technique is one of the promising tools widely used for material performance studies such as surface wear, corrosion, erosion etc., in the micrometer range using the charged particle induced nuclear reactions. In this technique, a small section of material is exposed to an energetic beam of charged particles, so as to produce a thin radioactive surface layer. The sensitivity of this technique is high due to its capability of low level radioactivity detection by γ-ray spectroscopy. Present work explores the TLA technique using γ-ray spectroscopy for several isotopes populated in different Heavy Ion (HI) reactions, which may be of interest for the reactor technology. Since, HI beam loses energy very quickly in the material, so it produces an extremely thin layer of activity in the surface. Aiming to investigate the surface wear study, we have measured the cross-sections of various reactions from several heavy ions induced reactions on isotopically pure targets 63,65Cu, 59Co, 93Nb, 121,123Sb, 130Te, 159Tb, 169Tm & 181Ta in order to apply HI activation in the TLA technique. The experimental cross-sections of nuclear reactions leading to residues are very important to be known for the yields of the products before its application in a particular material. Details will be presented.
