K x-ray satellite spectrum of Al by photon excitation

“…The present experimental energy difference E between the low-energy satellite K β1 and the diagram line K β L 0 works out to be 14.7 eV (table 3). This compares well with the values reported by Karlsson and Siegbahn [22], Fischer and Baun [10] and Schnell [11], though the value Fischer and Baun [10] obtained by electron excitation is a little bit higher. While the crossover theory [6] predicts a value of 22.4 eV for this energy difference, which is significantly higher, the molecular orbital model of Urch [7] estimates this value to be approximately 15 eV, which is nearer to the present value.…”

“…The present values of K α L 1 /K α L 0 and K α4 / K α3 intensity ratios agree well with the previously documented values [2,8,9,14,17,18,20,21]. However, [11] X-rays (Cr-tube) 1552.5 Fischer and Baun [10] Electrons 1553.6…”

“…Measurements are made in Al and Al 2 O 3 to look for chemical effects and also to study the low-energy K β satellite. There is a considerable difference between the relative intensity values of the K β satellite reported by Fischer and Baun [10] (electron excitation) and Schnell [11] (photon excitation). Schnell used gypsum as the analysing crystal.…”
