Rescattering photoelectron spectroscopy of CO2 molecule with an analytical returning electron wavepacket

Angle-resolved photoelectron momentum distributions of rescattering electron generated by intense infrared laser pulses were measured for CO2 molecules. It is shown that the measured distributions along the out-ermost backward rescattering caustic are well reproduced by calculations based on a newly developed factorization formula with the analytical returning photoelectron wave packet. © 2020 Journal of Physics: Conference Series.
