  We present the non-relativistic QCD (NRQCD) prediction for the polarization
of the J-Psi produced in b to J-Psi + X, as well as the helicity-summed
production rate. We propose that these observables provide a means of measuring
the three most important color-octet NRQCD matrix elements involved in J-Psi
production. Anticipating the measurement of the polarization parameter alpha,
we determine its expected range given current experimental bounds on the
color-octet matrix elements.
