L x-ray production cross sections in high-Z atoms by 3–5 MeV/u silicon ions
Total L x-ray production cross sections have been measured in 74 W, 79 Au, 82 Pb, and 83 Bi by impact of 3–5 MeV/u 28 Si ions, with different charge states q = 8 + up to 12 + . We find that the measured cross sections do not differ with the charge state of the projectile ions, but they vary with the...
