We discuss exclusive elastic double diffractive axial-vector chi(c)(1(+)) and tensor chi(c)(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 k(t)-factorization approach using unintegrated gluon distributions. Differential cross sections for different chi(c) polarizations are calculated. Angular distributions of J/psi meson from the radiative chi(c)(1(+),2(+)) decays are derived. Prospects for experimental selection of different spin states of chi(c) mesons are discussed.
