An electron is slowed down quickly from 10⁷ m/s to 0.5 * 10⁷ m/s, and a single photon is created in the process. Identify the radiation process (eg. Compton, positron emission, etc.) and compute the frequency and wavelength of the emitted photon.

Solutions

Expert Solution

As electron is a charged particle and it is slowed down from to , so, it is decelerated.
And we know that when a charged particle is slowed down by deceleration it radiates energy in the form of photons by Bremsstrahlung or in other words, braking radiation.

The change in the energy is



And as and the mass of the electron is , so, the change in the energy is


And from energy conservation, this energy is converted to the created photon energy. So, the frequency of the photon is


And the wavelength of the emitted photon is

Neutrons are born out of fission at a high energy and must be slowed down to the low energy region, called the “thermal energy” region, to cause another fission. A material called a “moderator” is used to slow the neutrons down, or “moderate” them, by elastic scattering collisions.The average neutron energy coming out of fission of thermal neutrons is 1.98 MeV in kinetic energy. What is the number of collisions required to bring its average kinetic energy to 0.1 eV...
