PROJECTILE CHARGE STATE DEPENDENCE OF TARGET L-ALPHA X-RAY-PRODUCTION

La x-ray production cross sections have been measured for thin solid targets of 60Nd, 67Ho, and 79Au (ρt<12 μg/cm2) for 1.86 MeV/amu 19 9F and 28 14Si, and 1.8 MeV/amu 35 17Cl ions as a function of the incident charge state. From the projectile charge state dependence of the cross sections, both direct ionization and electron capture contributions were extracted for a comparison to Coulomb ionization theories. The data provide supporting evidence for the theory of electron capture with a reduced binding effect. Copyright © 1978 by The Institute of Electrical and Electronics Engineers, Inc.
