The Klein-Gordon (KG) Scalar Relativistic Wave Equation

{\mathbf Remarks:} The KG-equation is a Lorentz invariant expression. For specific computations of specific cases it can only be utilized with the appropriate boundary conditions.

1.1. The Klein-Gordon equation

The Klein-Gordon equation is an equation of mathematical physics that describes spinless (spin-0 particles). It is given by:

$\Box \psi =\left({\frac {mc}{\hbar }}\right)^{2}\psi$

Here the $\Box$ symbol refers to the wave operator, or D'Alembertian, ($\Box =\nabla ^{2}-{\frac {1}{c^{2}}}\partial _{t}^{2}$) and $\psi$ is the wave function of a spinless particle.
