Triple differential cross-section for Laser-assisted (e,2e) process on molecule by Plane and Twisted electrons Impact
Neha, Rakesh Choubisa
Twisted electron-impact single ionization ((e,2e) process) of water molecule is theoretically studied in the presence of an external laser field. Calculations have been performed i…
