Abstract

In the foregoing discussion of nuclear phenomena a number of elementary particles have been encountered and some features of their interactions have been described. Each of these particles can be characterized by its spin J, its electric charge (usually denoted by superfixes +, 0, -) and the interactions — strong, electromagnetic, weak — it experiences. These particles include:
  1. 1.

    the neutron and proton (n,p; J = ½) which experience all three basic interactions;

     
  2. 2.

    the pions (π+, π0, π-; J = 0) which experience all three basic interactions;

     
  3. 3.

    the electron and positron (e+, e-; J = ½) which experience the electromagnetic and weak interactions;

     
  4. 4.

    the neutrino and antineutrino (ve, v͂e; J = ½) which experience only the weak interaction;

     
  5. 5.

    the photon (γ; J = 1) which experiences only the electromagnetic interaction.
