Description: In this article, M-shell x-ray-production cross sections are reported for ₁¹H+ and ₂⁴He+ ions incident on thin targets of ₇₉Au, ₈₂Pb, ₈₃Bi, and ₉₂U. The energy of the ions ranged from 0.3 to 2.6 MeV in increments of 0.1 MeV. The first Born calculations overpredict the data at all energies studied. The perturbed-stationary-state calculations with energy loss, Coulomb deflection, and relativistic effects agree with the present data for both ₁¹H+ and ₂⁴He+ ions at ~0.35 MeV/u, overpredict the data at higher E₁/A₁, and underpredict the data at lower E₁/A₁. The electron-capture contribution to the target ionization is calculated to be less than 3.4% for the targets, projectiles, and energies reported in this work.
