The L alpha/L beta, L alpha/L gamma, Ll/L beta, Ll/L gamma and L beta/L gamma intensity ratios were measured by measuring the characteristic X-ray intensities in 24 elements over the range 57 less than or equal to Z less than or equal to 92 using a 100 mCi Am-241 filtered source for excitation. A comparison is made of the experimental results with the calculated values obtained by using theoretical X-ray emission rates, subshell photoionisation cross sections, subshell fluorescence yields and Coster-Kronig transition probabilities. A fairly good agreement is observed between experimental and theoretical values. The experimental and theoretical values of these ratios versus Z were fitted. The enhancement effect of K to Li subshell vacancy transfer on relative L X-ray intensities are shown in these curves.
