If I have a wave function [itex]\Psi(x,x')[/itex] for two identical fermions, then I have learned that the particle density at [itex]x[/itex] is(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

n(x)=2\int|\Psi(x,x')|^2dx'

[/tex]

[itex]|\Psi(x,x')|^2[/itex] is the probability density of finding a particle at [itex]x[/itex] and a particle at [itex]x'[/itex]. Does this mean that [itex]\int|\Psi(x,x')|^2dx'[/itex] is the probability density of finding a particle at [itex]x[/itex] ?
