We consider exclusive double diffractive production of polarised axial-vector
Οcβ(1+) and tensor Οcβ(2+) charmonia in proton-(anti)proton
collisions at Tevatron energy. The corresponding amplitudes for these processes
are derived within the ktβ-factorisation approach. Contributions from
different polarisation states of axial-vector and tensor charmonia are
quantified. Corresponding experimental consequences are discussed.Comment: 3 pages, 3 figures, talk given at 11th International Workshop on
