We present a quantum study of stereodynamics of the 18O + (OO)-O-16-O-16(v = 0,j = 1) -> (OO)-O-16-O-18 (v' =O,j') + O-16 exchange reaction at a collision energy E-coll = 0.01 eV. Polarization moments of the reactants have been computed and stereodynamical portraits have been generated. The results show that the reactant preferred relative orientations are strongly dependent on the scattering angle and on the product rotational states. (C) 2017 Elsevier B.V. All rights reserved
