Strong Laser Field Induced Modifications of Electron-Transfer Processes in Ne⁺-He Collisions

A strong laser field ( ≈ 10¹⁵ W/cm²) induced low-collisional-energy charge transfer process in Ne⁺-He system is explored. In the low collisional energy regime, the cross-section can be ≈ 10¯¹⁷ cm² which is about two orders of magnitude higher than the collision-only process. With increasing collisional energy the cross-section curve displays flattens and the charge capture tends to be practically independent of the laser detuning. In addition, we find that the capture probability in this Ne⁺-He system varies significantly with the laser polarization angle.
