Collisions between linear polar molecules trapped in a microwave field

Atomic and Molecular Collisions

Abstract.

The collisions between linear polar molecules, trapped in a microwave field with circular polarization, are theoretically analyzed. We demonstrate that the collisional dynamics is mostly controlled by two ratios ν/B and x=μ0E0/ħ B (ν is the microwave frequency, B is the molecular rotational constant, μ0 is the dipole moment, and E0 is the electric field amplitude). We discuss the dependence of collision cross sections on these ratios in order to find an advantageous condition for evaporative cooling.
