“…While PIXE originated and continues using light ions such as protons or alphas [6][7][8][9][10][11][12][13][14][15][16],there is an increasing interest to use heavy ions for PIXE analysis due to higher cross sections and thereby better sensitivity [17]. While discrepancies between theories and experiment were attributed to multiple ionization even with protons [18], multiple-ionization effect has been known for decades in L-shell ionization by heavier ions [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. However this effect is still rarely addressed for the x-ray emission elemental analysis in the aftermath of ionization by such ions.…”

L shell line and total x-ray production cross sections in 78Pt, 79Au, 82Pb, 83Bi, 90Th, and 92U targets ionized by 4-6 MeV/u fluorine ions were measured. These cross sections are compared with available theories for L shell ionization using single-and multiple-hole fluorescence and the Coster-Kronig yields. The ECPSSR and the ECUSAR theories exhibit good agreement with the measured data, whereas, the FBA theory overestimates them by a factor of two. Although for the F ion charge states q = 6-8 the multiple-hole atomic parameters do not significantly differ from the single-hole values, after an account for the multiple-holes, our data are better in agreement with the ECUSAR than the ECPSSR theory.

“…The measurement of K-shell ionization cross-sections of Cr, Ni and Cu was performed by Llovet et al (2000) by impact of 6.5-40 keV electrons. Furthermore, the measurements of L shell photoionization cross-sections were carried out by many researchers (Yu et al, 1997;Hallak, 1998;Al-Saleh and Saleh, 1999;Mandal et al, 2001;Wu et al, 2007;Puri et al, 1996). Chemical effects on L X-ray fluorescence cross-sections of Ba, La and Ce compounds were investigated by Baydas -et al, (1999).…”
