Total quantum state in the Einstein-Podolsky-Rosen-Bohm experiment with identical particles

The spin state in the Einstein-Podolsky-Rosen-Bohm gedankenexperiment with identical particles is supplemented by the spatial part. This allows one to extract all the information needed in a typical EPR argument, without requiring semi-intuitive steps. Local spin operators are introduced, to describe measurements of spin in given regions of space.
