    • Note of caution: The ICRU's currently recommended I values are those given in Report 37. They have been reprinted in Reports 49 (1993) and 73 (2005). However, confusion has arisen because Report 73 also gives mean excitation energies calculated with the PASS code for energy loss of heavy ions. The latter are not ICRU's recommended values. Since I values are of secondary importance for heavy-ion energy loss, approximate values suffice and for simplicity the PASS code employs approximations to the optical oscillator strength density. For example, Henke's empirical model for X-ray scattering functions is used at X-ray energies. This model relies on the approximate power-law dependence of X-ray absorption with energy in regions far from edges. However, it is not reliable near edges, the very regions that give the major contributions to the integrals in Eq. (9) for I. The resulting I values, while sufficiently accurate for heavy-ion energy-loss calculations, are specific to the PASS code, but they differ significantly from both the ICRU's recommended values and from the I values calculated here directly from measured optical and X-ray oscillator strengths.
