Cross sections for {ital K} x-ray production in solid targets ({ital Z}=13, 22, 26, 29, 32, 40, 42, 46, and 50) by 30-MeV/amu beams of H, N, Ne, and Ar were measured. The cross sections were determined by recording the spectra of {ital K} x rays with a Si(Li) detector in coincidence with beam particles detected in a microchannel plate assembly. The {ital K}-shell-ionization cross sections deduced from these data agree quite well with the predictions of the perturbed-stationary-state theory with energy loss, Coulomb deflection, and relativistic corrections. Detailed analyses of the projectile and target {ital Z} dependences of the cross sections were performed. Also, the relative intensities of {ital K} x rays from double {ital K}-shell ionization of the higher-{ital Z} targets are presented for N, Ne, and Ar projectiles.
