Not true in general. It is true for fermions (particles with spin

(2i+1)/2) and is known as the Pauli exclusion principle. For bosons

(particles with integral spin) particles can, and do, occupy precisely

the same state at the same time. It's why lasers, superfluids and

superconductors have such interesting properties.

I fail to see what any of this has to do with factorization, but it will

be interesting to see if anything comes from it.
