Beta decay is nuclear decay in which an electron is emitted from an atom. If the electron is given 0.85 MeV of kinetic energy, what is its velocity, as a fraction of the speed of light? You will have to assume the electron is moving relativistically.

In certain radioactive beta decay processes, the beta particle (an electron) leaves the atomic nucleus with a speed of99.95% the speed of light relative to the decaying nucleus. In the laboratory frame, the nucleus is moving at 75.00% the speed of light, and the electron is emitted in the same direction the nucleus is moving. Find the energy and momentum of the electron as measured in the laboratory frame and in the rest frame of the decaying nucleus.

When a fast electron (i.e., one moving at a relativistic speed) passes by a heavy atom, it interacts with the atom's electric field. As a result, the electron's kinetic energy is reduced, the electron slows down in the meantime, a photon of light is emitted. The kinetic energy lost by the electron equals the energy E_r of a photon of radiated light. E = K - K', where K and K' are the kinetic energies of the electron before and...

(Figure 1) shows the decay scheme for 137Cs, which has two possible beta decay modes. The first, labeled β1, is a decay directly to the ground state of 137Ba. The second beta decay (β2) is to an excited state 137Ba∗. This excited state subsequently undergoes gamma decay to the ground state. In beta decay, the maximum possible energy of the emitted beta particle is equal to the difference in energy between the initial and final states of the nucleus. The...

6. One form of nuclear radiation, beta decay, occurs when a neutron changes into a proton, an electron, and a neutral particle called an antineutrino: n → pt + e + De, where ve is the symbol for an antineutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the electron and neutrino are ejected from the nucleus. The ejected electron is called a...
