Abstract
We study the origin of the cusp structure in the transverse or lateral electron momentum distribution (TEMD) for the process of tunneling ionization driven by a linearly polarized laser pulse. We show that the appearance of the cusp in the TEMD can be explained as follows. Projection on the set of the Coulomb scattering states leads to the appearance of elementary cusps which have a simple structure as functions of the lateral momentum. This structure is independent of the detailed dynamics of the ionization process and can be described analytically. These elementary cusps can be used to describe the cusp structure in TEMD. ©2015 American Physical Society
