单词 | Klein-Gordon equation |
释义 | Klein-Gordon equation An equation in relativistic quantum mechanics for spin-zero particles. The Klein-Gordon equation has the form [□ - (mc/ℏ)2]ψ =0 ,where □ = ∇2 - (1/c2)(∂/∂t2), and ∇2 is the Laplace operator (see Laplace equation), m is the mass of the particle, c is the speed of light, ℏ is the Dirac constant (see Planck constant), and ψ is the wave function of the particle. This equation was discovered by several authors independently, including Oskar Klein (1894–1977) and Walter Gordon (1893–1940) in 1926. The Klein-Gordon equation is not viable as an equation in single-particle relativistic quantum mechanics but does describe spin-zero particles, such as mesons; it includes the prediction of the existence of antiparticles for such particles.
