WebThe mass of the electron equal to the mass of the positron is \rm 0.000548756 \ amu 0.000548756 amu. In kilograms, the exact value of the positron mass is about \rm 9.11 \times 10^ {-31} \ kg 9.11× 10−31 kg . The positron is produced by the departing neutron in the radioactive decay and their kinetic energy is supported by the motion. WebThe photon energy and momentum are proportional. Now, for a time-like four-momentum, the 'length' of the four-momentum is non-zero and is proportional to the invariant mass of the particle E 2 − ( p c) 2 = ( m c 2) 2 This is the origin of the relativistic energy-momentum relation E = ( p c) 2 + ( m c 2) 2

When a photon interacts with an atom, three things can happen: elastic scattering, the photon keeps its energy and changes angle. inelastic scattering, the photon gives part of its energy to the atom and changes angle. absorption, the photon gives all its energy to the absorbing atom, and the absorbing electron moves to a higher energy level ...
