英文摘要 |
Light-ion-impact ionizations were investigated for the atomic K-shell on target elements with Z = 27 - 29 for incident protons, deuterons, 3He- and 4He- ions. X-ray production cross sections u, were measured as a function of incident energies 0.7-1.5 MeV/amu in steps of 0.1 MeV/amu. Systematic behavior of excitation functions and cross section ratios σx(l)/σx (2) measured with two types of projectiles of Z = 1 - 2 ions at same MeV/amu were examined. Two theoretical calculations of the first Born approximation (PWBA+OBKN) and the ECPSSR theories were performed. The results obtained from the experimental data and the theoretical calculations are compared and discussed. |
