Research Abstract

We have measured angle-resolved high-energy rescattering electron spectra of simple molecules induced by intense femtosecond laser pulses. Differential cross sections of electron-parent ion elastic scatterings are extracted from the electron momentum distributions of rescattering electrons and compared with theoretical calculations. The good agreement between the experimental and theoretical calculations indicates that the present procedure can be used to obtain the structural information of the molecules using femtosecond laser light.
