Relativistic Wave Equation for Spin-O Particles The Klein-Gordon Equation and Its Applications

  • Walter Greiner

Abstract

The description of phenomena at high energies requires the investigation of relativistic wave equations. This means equations which are invariant under Lorentz transformations. The transition from a nonrelativistic to a relativistic description implies that several concepts of the nonrelativistic theory have to be reinvestigated, in particular:
  1. 1)

    Spatial and temporal coordinates have to be treated equally within the theory.

     
  2. 2)
    Since
    $$ \Delta x \sim \frac{\hbar }{{\Delta p}} \sim \frac{\hbar }{{m_\text{0} c}} $$
    , a relativistic particle cannot be localized more accurately than ≈ ħ/m 0 c; otherwise pair creation occurs for E > 2m 0 c 2. Thus, the idea of a free particle only makes sense, if the particle is not confined by external constraints to a volume which is smaller than approximately the Compton wavelength λc = ħ/m 0 c. Otherwise the particle automatically has companions due to particle-antiparticle creation.
