    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 Lα_{\alpha}/Ll intensity ratios obtained in the present work are in good agreement with theoretical values while the Lβ_{\beta }/Lγ_{\gamma } and Lα_{\alpha }/Lβ_{\beta } 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
