DefinitionA <COMPTON WAVELENGTH> is a <Property> that is a quantum mechanical property of a particle equal to the wavelength of a photon whose energy is the same as the mass of that particle; it is calculated as lambda_C = h/(m.c_0) where h is a <PLANCK CONSTANT> , m is a <REST MASS> and c_0 is a <SPEED OF LIGHT> in a <VACUUM>
