In the present work we consider the Argon photoionization from the subshells 3s, 3p0 and 3p1 due to a short XUV pulse assisted by an IR laser both linearly polarized. Within the continuum-distorted wave Strong Field Approximation (SFA) supported by the ab initio solution of the time-dependent Schrödinger equation (TDSE) we study the angle-resolved momentum distribution of photoelectron for the case that both fields are linearly polarized. We analyze and characterize the modulation of both factors, the intra- and intercycle contributions, on the spectrum.
