Abstract
We find that single spin asymmetries in nonrelativistic QCD are nonvanishing in general. They are proportional to the imaginary parts of some nonperturbative matrix elements. With statistics of about 106 identified J/ψ 's, or 105 identified Χ2, it is possible to measure these imaginary parts even if they are an order of magnitude smaller than the real parts. Such statistics are quite reasonable at polarized HERA N and other future experiments.
