Functional description of effective beam. Relative intensity versus atomic number effective beam spectra with and without attenuation of the incident spectrum. Based on the result in equation (10). The functional form is in red, data are shown with their uncertainties. Attenuation (b) increases the minimum energy of the spectrum, which introduces a `kink' in the effective beam spectrum. The non-attenuated result (a) captures the general trend of the data, but not its details. |
