L-Shell Ionization in High-Z Targets by Carbon and Silicon Ions

摘要

L-shell ionization in Ho, Er, Tm, Ta, W, Tl, Pb and Bi by 20 MeV carbon ions and 37.5 MeV silicon ions has been investigated. The observed L/sub alpha /L/sub gamma / x-ray intensity ratios are compared with the estimates based on PWBA and BEA calculations. The energy shifts in the L/sub alpha /, L/sub gamma sub 1 / and L/sub gamma sub 4 / x rays are attributed to the presence of M shell spectator vacancies.
