Percentage correction to the measured [μ/ρ]. The bandwidth of the incident beam. Here a small finite bandwidth (1.57 eV) measured with an accuracy of 0.03 eV (model-dependent) permits the effect of 1.4% on the absorption measurement to be corrected, and thereby a platform-independent absorption coefficient to be obtained (de Jonge et al., 2004). Cross symbols, plus-sign symbols and diamond symbols refer to corrections relating to three foils of different thicknesses: 10, 50 and 25 µm, respectively. |
