主　　题：collision anion symmetry 

摘      要：The atom-atom-anion three-body recombination(TBR)and collision induced dissociation(CID)processes of the^(3)He-^(3)He-T^(-)system at ultracold temperatures are investigated by solving the Schr¨odinger equation in the adiabatic hyperspherical *** variations of the TBR and CID rates with the collision energies in the ultracold temperatures are *** is found that the J~Π=1~-symmetry dominates the TBR and CID processes in most of the considered collision energy *** rate of TBR(CID)into(from)the l=1 anion is larger than those for the l=0 and l=2 anions,with the l representing the rotational quantum number of~3HeT~-.This can be understood via the nonadiabatic couplings among the different channels.
