Question

QUESTION 48 During an interaction with an N-shell electron of a tungsten atom, an X-ray is scattered with 15 keV of energy and the electron is ejected with 11.7 keV of kinetic energy. What was the energy of the incident X-ray? Give your answer in keV, rounded to the nearest tenth. But do not include the unit - give only the number portion of your answer. Approximate Number binding of energy Shell electrons (kov) 0.3 L 4 0.01 Carbon- 37 ZO 1.3 0.3 0.04 Barium-18 Ba 2.8 ZO 0.6 0.08 N Tungsten 1 W
