Detailed dynamics of direct three-body recombination of singly charged ions.

We consider the main aspects of detailed dynamics of the reactions of direct three-body ion-ion recombination Cs + X + R → CsX + R (X = F, I and R = Ar, Xe) for non-central encounters of the ions. The reactions are simulated by the quasiclassical trajectory method using diabatic semiempirical potential energy surfaces proposed previously. The recombination mechanisms are studied visualization of randomly selected trajectories for each of the four systems.

Dynamics of third order direct three-body recombination of heavy ions.

The direct three-body recombination reactions Cs + X + R → CsX + R (X = F, I and R = Ar, Xe) are studied within the quasiclassical trajectory method using diabatic semiempirical potential energy surfaces, the encounters of the ions being non-central. The collision energies range between 1 and 10 eV (values typical for low temperature plasma), while the so-called delay parameter, which characterizes the delay in the arrival of the neutral atom R in relation to the time instant when the distance between the ions attains its minimum, is equal to 0 or 20%. The calculation results include the recombination excitation functions, the opacity functions, and the vibrational and rotational energy distributions of the recombination products.
