CU K X-RAY-PRODUCTION AS A FUNCTION OF PROJECTILE ATOMIC NUMBER, ENERGY, AND INCIDENT CHARGE STATE

Cu K x-ray production cross sections for 1.7-MeV/amu C, N, O, and F ions were determined in the limit of vanishingly thin solid Cu targets. These data were used in a systematic study of the Z1 dependence of Cu K x-ray production for projectiles from H to Cl at 1.7 MeV/amu. Studies of the energy dependence of Cu K x-ray production for F ions at 1.7, 2.0, 2.2, and 2.5 MeV/amu were also made for incident projectiles with 0, 1, and 2 initial K-shell vacancies. These data require the inclusion of electron transfer from the target K shell to the projectile in addition to direct ionization of the target in order to explain the charge-state and Z1 dependences of the x-ray-production cross sections. © 1979 The American Physical Society.
