Multiple ionization effects on L X-ray intensity ratios in Hf, Ta, Re, Ir, Pt, Au and Pb due to proton bombardment at energies 1–5 MeV
The L X-ray intensity ratios in the elements Hf, Ta, Re, Ir, Pt, Au and Pb
due to proton bombardment at energies from 1 to 5 MeV are measured and
compared with the ECPSSR theoretical intensity ratios. The L/Ll intensity ratios obtained in the present work are in good
agreement with theoretical values while the L/L and
L/L intensity ratios are consistently lower than the
theoretical values. This deviation may be explained in terms of multiple
ionization effects in M, N and O shells
