WHAT ARE BOSONS

Definition -

Bosons are the particles of the system whose energy spectrum can be explained on the basis of BE statistics . Bosons do not obey Pauli's exclusion principle . That is two or more particles can exists in the same energy level . The bosons have integral spin -

Examples of bosons are as under :
  1. Photons ( spin 1 )
  2. K and π mesons ( spin 0 )
  3. Atoms like helium , total spin of  whose electrons , protons and neutrons is integral .
  4. Photons , that is quanta of light waves (spin 1 )
