Surface wear studies in some materials using α-induced reactions

The radio-activity produced during the irradiation of ^63,65Cu, ⁵⁹Co, ⁹³ Nb and ^121,123 Sb targets with -particles have been measured using activation technique. The yields of radioactive isotopic products ^66,67,68Ga, ⁶¹ Cu, ⁹⁶g,m Tc and^123,124,126 I have been determined in the energy range ≈ 10-40 MeV using stacked foil technique. Radioactive counting of amples was performed with a high-resolution gamma-spectrometer. As light ion beams produce an extremely narrow layer of activities in the surface of a material, these reactions may be useful for thin layer activation study. 

Keywords:- activation technique, excitation functions, alpha inducedreactions, thin layer activation analysis.
