Abstract

The L 3l, L 3α, L 3β , L 2β, L 2γ, L 1β and L 1 γ X-ray production cross-sections in Hg and Au have been measured using the 59.5 keV incident photon energy. The measurements were performed using the 241Am radioisotopes as photon sources and a Si(L i ) detector. The L X-rays are resolved with a new analytical method. The obtained L 3l, L 3α, L 3β, L 2β, L 2γ , L 1 β and L 1 γ X-rays were compared with the theoretical calculations using the most reliable theoretical values of L i (i=1,2,3) subshell photoionisation cross-sections, fluorescence yields, X-ray emission rates and Coster–Kronig transition probabilities. Furthermore, the Coster–Kronig transition probability ( f 12) was measured using the L 2 γ X-ray production cross-section. The results in the present paper are found to be in good agreement with the calculated values.
