Trajectory analysis for explanation of the V-like structure in the correlated electron momentum distribution for nonsequential double ionization of Helium

Abstract

In this paper, we deeply investigate the evolution of the ionized electrons of He in laser field by trajectory-analysis method to understand the physical dynamics of the asymmetric energy sharing process. The results show that the discrepancy in transverse momentum spectra of the recolliding and bound electrons not only serves as a signature of this process, but provides insight into the attosecond three-body interactions
