New measurements of Mαβ , Mγ and M-shell X-ray production cross sections induced by carbon ions on Bi and Pt targets

In the present work, the Mαβ , Mγ and M shell X- ray production cross sections for the elements Pt and Bi have been measured by C4, 3+ ions in the energy range 1.5 MeV to 5 MeV. X-ray and elastic backscattered spectra from thin Pt and Bi targets were simultaneously measured and X-ray production cross sections were extracted from collected spectra. The obtained results have been compared with the theoretical calculations based on Semi-classical Approximations (United Atom – Separated Atom) model [1], the PWBA (Plane Wave Born approximation)[2] and the ECPSSR [3] model including the effects of the binding energy, relativistic, colomb deflection and energy-loss. The ISICS code is used for PWBA and ECPSSR calculations [4]. References [1] D. Trautmann and T. Kauer, Nucl. Instr. And Meth. B (42), 1989, 449. [2] E. Merzbacher and H.W.
