N., "Control of atomic dynamics in laser-assisted electron-atom scattering through the driving-laser ellipticity" (2013). Anthony F. Starace Publications. 194. Orders of magnitude increases of the cross sections are predicted for laser-assisted low-energy electron-atom scattering (accompanied by absorption of laser photons) as the laser ellipticity is increased. These ellipticitycontrolled enhancements are

The strong sensitivity of laser-assisted scattering cross sections to this dynamics and the laser ellipticity is illustrated for e-Ne and e-Ar scattering in both midinfrared (λ = 3.5 µm) and CO 2 (λ = 10.6 µm) laser fields of moderate intensities.
