摘要：
K-shell x-ray production cross sections have been measured for elements of Ti, Mn, Co, Ni, Cu, Zn and Ga (Z = 22-31) using He-4-ion beams in the energy range 1.5-6.0 MeV. Results are compared with the predictions of the first-order Born approximation (FOBORN) and the energy-loss Coulomb-deflection perturbed-stationary-state relativistic theory (ECPSSR), and those of earlier measurements. The agreement with the ECPSSR theory is within 10%. In addition to the experimental cross sections, the K(beta)/K(alpha) X-ray yield ratios have been extracted, and compared with the calculated values of Scofield, and the "recommended" values of Khan and Karimi.
