摘要
Abstract
The x-ray production cross section ratios Lβ/Lα of elements Hf and W were measured as functions of electron ener-gies(from threshold up to 32 keV). The experimental results showed that ratio Lβ/Lα at near threshold depends directly on in-coming energy,which differs entirely from available L-shell data at higher energies and those on K-shell. Comparison with otherresults published and both theoretical predications have been performed.关键词
