Collisional Quantum Interference on Rotational Energy Transfer: Relationship between Interference Angle and Relative Velocity

doi: 10.1088/1674-0068/15/3/175-180

Abstract: A dynamic model of collisional quantum interference (CQI) on rotational energy transfer in an atom-diatom system has been described by Sun et al., based on the first order Born approximation of time dependent perturbation theory and long-range interaction potential. The experiment CO A 1Π~e 3Σ- collision with He in a static cell has been simulated successfully. To obtain directly the relationship between interference angle and relative velocity from experiment, an experiment is proposed by Sha, using molecular beam and velocity imaging technology. As a theoretical study of the relationship between interference angle and relative velocity, the interference angles are calculated with different relative velocities, and the changing tendency is obtained. It is revelatory for the molecular beam experiment to measure directly the interference angles by controlling the relative velocities.
