 P: 66 How do I find the endpoint energy for photons when an .75 MeV electron beams stops inside a tungsten target? I just don't understand how to solve it without the scattering angle.
 Admin P: 21,399 No scattering angles means the angle is zero? The scattering angle varies from 0 to 180° (0 to $\pi$). http://hyperphysics.phy-astr.gsu.edu...mptint.html#c1 http://hyperphysics.phy-astr.gsu.edu...compeq.html#c1 Here is a characteristic X-ray for tungsten at 100 kV. http://www.bh.rmit.edu.au/mrs/subjec...xray.html#Fig4 Is the energy supposed to be 0.75 MeV!? or 0.075 MeV (75 keV)? Perhaps I am not understanding the question.
 P: 66 Here is the exact question, from a notoriously vague teacher: A .75 MeV electron beam strikes and stops inside a tungsten target. a. Determine the endpoint energy for the photons. b. Determine the momentum of the hiest energy photons. c. Determine the wavelength of the end-point photons. Wouldn't an angle of 0 make the equation (lamda2-lamda1=(h/mc)(1-cos(0))) go to 0?
