  "abstract": "We have measured the polarization of J/Psi and Psi(2S) mesons produced in p\\bar{p} collisions at \\sqrt{s} = 1.8 TeV, using data collected at CDF during 1992-95. The polarization of promptly produced J/Psi [Psi(2S)] mesons is isolated from those produced in B-hadron decay, and measured over the kinematic range 4[5.5] < P_T < 20 GeV/c and |y| < 0.6. For P_T \\gessim 12 GeV/c we do not observe significant polarization in the prompt component.",
