Solution to the Klein Gordon Equation

In summary, the conversation revolved around the general solution for the Klein Gordon equation, which was given as ψ(r,t)= e^i(kr-ωt) under certain constraints. One person asked if the solution was valid and mentioned their confusion about the imaginary term in the de Moivre formula when calculating probability. Another person clarified that the correct way to calculate probability is ψ*ψ, not ψ2. The conversation ended with gratitude for the clarification.

Hey guys, I was reading up on the Klein Gordon equation and I came across an article that gave a general solution as: [tex]\psi[/tex](r,t)= e^i(kr-[tex]\omega[/tex]t), under the constraint that -k^2 + [tex]\omega[/tex]^2/c^2 = m^2c^2/[tex]\hbar[/tex]^2, forgive my lack of latex hah.

Through Euler's law this does give a solution tantamount to cos(kr-[tex]\omega[/tex]t)+isin(kr-[tex]\omega[/tex]t).

My question is simply.. is this valid? I ask because if you were to integrate the square over an interval you should get a probability, however the imaginary term will carry through from the de Moivre formula. I'm terribly confused.

Thanks guys!

no, the probability is ψ*ψ, not ψ2 :wink:
