Quizplus · Accepted Answer

The kinetic energy of the incident electron must be greater than that of the electron it knocks from its orbit in order to remove it from the atom and create a characteristic interaction. If the energy is less than that of the electron in the orbit, elastic scattering occurs instead. Proportional or characteristic energy are not correct choices.
