  The nucleon electromagnetic form factors G_E and G_M are complex quantities
in the time-like region. The absolute values can be determined by measuring the
angular distribution of the nucleons in e^+ e^- --> N N-bar. The complex phase
can only be determined by measuring one or more polarizations of the initial or
final state. For PEP-N, we can use unpolarized e+ and e- and measure the
polarization of one of the outgoing nucleons.
