摘要：
L-subshell X-rays of some rare-earth elements of Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu were measured for 2 MeV He-4(2+) ion bombardment. The dependence on the atomic number of X-ray ionization cross sections of the above elements using different data bases for the fluorescence yield and Coster-Kronig transitions are examined. The same effect on theoretical calculations of the relative intensities of individual lines in the X-ray spectrum is presented for the ECPSSR theory and its extensions, namely, ECPSSR-IS and ECPSSR-IS-UA.
