Suppose that a pair of electrons, A and B, were described by the following wave function: (see attached for equations).

(I have rewritten this equation as I believe some of you are having problems reading the text.)

What property specific to entanglement must the wavefunction describing an entangled state of two particles A and B possess? Using this criterion, determine whether or not the wavefunction above describes an entangled state.

See attachment for full question and details.
