We discuss exclusive elastic double diffractive axial-vector \ensuremathχc(1+) and tensor \ensuremathχc(2+) mesons production for different meson polarizations in proton-(anti)proton collisions at the Tevatron energy. The amplitude for the process is derived within the kt-factorization approach using unintegrated gluon distributions. Differential cross sections for different \ensuremathχc polarizations are calculated. Angular distributions of J/\ensuremathψ meson from the radiative \ensuremathχc(1+,2+) decays are derived. Prospects for experimental selection of different spin states of \ensuremathχc mesons are discussed.
