The maximum kinetic energy that an alpha particle can transmit to an electron occurs during a head-on collision. Compute the kinetic energy lost by an alpha particle of kinetic energy 7.4 MeV in a head-on collision with an electron at rest. x MeV Enter a number. Are we justified in neglecting this energy in the Rutherford theory? No, because the kinetic energy lost by the alpha particle is more than 5% of its initial kinetic energy. Yes, because the kinetic...
