• a) What is the energy of the scattered photon? 
• 
  
• b) What is the wavelength of the scattered photon?
• 
  
• c) What is the momentum of the scattered photon (in J×s/m)?
• 
  
• d) What is the kinetic energy of the recoil electron, assuming it is the most easily ionized electron that is ejected? 
• 
  
• e) What is the momentum of the recoil electron (in J×s/m)?
• 
  
• f) What is the average distance that the 1.3 MeV photon traveled in carbon before it Compton scattered? 
• 
  
•  g) How thick do you need to make the carbon to have a 90% chance of absorbing the full 1.3 MeV gamma ray?

Answer rating: 100% (QA)

a The energy of the scattered photon can be calculated using the Compton formula Escattered Eincident hmc 1 cos where Eincident is the energy of the incident photon 13 MeV h is Plancks constant 6626 x ... View the full answer
