Abstract

Lgamma X-ray emission from Bi bombarded by O ions of 10 and 20 MeV and Ne ions of 88 MeV has been studied with a Si(Li) detector. The observed Lgamma X-ray spectra have been decomposed into the six transition lines of Lgamma 5, Lgamma 1, Lgamma 2 and Lgamma 3 (L-N transition), and Lgamma 6 and L gamma 4,4(inf)/ (L-O transition), with an assumption that the energy shifts of these lines can be sorted into two groups corresponding to the L-N and L-O transitions and have the same shift in each group. The degree of N-shell multiple ionisation has been deduced from the energy shift determined for the L-O transition. The results have revealed the presence of nearly the same number of N-shell vacancies, ten to thirteen, prior to the L X-ray emission for all the ion bombardments investigated. Some indication on the O-shell multiple ionisation is given.
