Solve exercise: Bethe-Bloch for alpha particles

Energy loss by electrons, positrons: 

  • ionisation effects 
  • bremstrahlung radiation: dependance on Z, screening effect and critical energy 
  • radiation length X0 
  • Other types of scattering: Moller, Bhabha, annihilation 

Energy loss by gammas:  

  • photoelectric effect 
  • Compton scattering 
  • Pair creation
