Absolute cross sections have been measured for the K-shell ionization of Al, V, Fc, Cu, Y, Ho, Ag, and Sn by a-particle bombardment over the 1-5-MeV energy range. Characteristic x-ray radiation produced by the ion impact was detected by a cooled Si(Li) detector. Experimental results are compared with ionization cross sections calculated using the plane-wave Born approximation, the semiclaasical approach, and the binary-encounter approximation (BEA). The present results agree most favorably with the BEA calculations. Comparisons of cross sections obtained from separate thick- and thin-target measurements show excellent agreement.
